  • the Peltier element(s) 7 consist of ceramic or metal plates, which are connected by soldering, gluing, or pressing to the cavity strip(s) 10 and, on the other hand, to the heat reservoir 1, ensuring rapid and low-loss heat flow.
  • additional insulation 9 is arranged between the different temperature zones.
  • heat conductors, heat pipes 6, heat foils, thermal pastes, heat spreaders and/or vapor chambers are embedded inside the cavity strip 10, the heat reservoir 1, or arrangeable heat dissipation strips.

  • one or more cavity strips 10 can form a temperature zone, which are distributed in strips and separated from each other by thermal insulators 9.
  • thermal insulators 9 Several heat pipes 6, heat spreaders, and/or vapor chambers can be embedded inside a cavity strip 10 to accelerate the heat transfer to the heat reservoir 1 and the propagation speed of the heat flows during heating and cooling.

  • Compact precision thermocyclers can operate in a device configuration with an automated inverted or upright light or fluorescence microscope, with an upstream station for loading samples into the cavities (sample receiving openings 14), a transport device (tray, conveyor belt) for the targeted movement and positioning of one, or two or more compact precision thermocyclers, and a second station for analysis equipped with at least one microscope and an evaluation device, such as a camera.
  • the cavity strips 10 are force-fitted with reaction chambers containing at least the reaction solution and/or a sample. Temperature control is achieved via thermally connected heat conductors multidirectionally between the sample, cavity strip 10, Peltier element 7, heat reservoir 1, and, if required, a second heat reservoir 5 in an energy-saving and controllable manner, so that recuperation occurs during successive heating and cooling cycles.
  • This makes it possible for heat to be released passively or actively to an ambient medium, such as the ambient air, at an accelerated rate as needed. In principle, however, analysis can also be performed under a different protective medium.

  • ThermoCycler makes it possible to To thermally start, appropriately control, or precisely terminate reaction solutions in order to conduct polymerase chain reactions, ligase chain reactions, isothermal nucleic acid amplifications, and melting curve analyses of nucleic acids and proteins.
  • the integrated microcomputer 4 contains control software with comprehensive algorithms that regulates the process in such a way that heat can be transferred from the heat reservoir 1 via the heat conduction system and from the Peltier element 7 into the sample with very little loss and quickly, and then dissipated back into the heat reservoir 1 or the respective arranged heat reservoirs, in order to realize rapid thermal cycles in the sample with the greatest possible energy efficiency.
  • the heat reservoirs 1 and 5 are set to a temperature between the upper temperature level (denaturation at 94-96° C) and the room temperature (at 25° C) and the small temperature differences to be bridged are controlled by means of Peltier elements 7.
  • the advantage of the solution according to the invention lies in the fact that the heat loss occurring during operation of the Peltier elements 7 is not dissipated through intensive cooling during each cycle, as was previously the case, but is temporarily stored directly in the ThermoCycler. This is because it is complex and expensive to repeatedly dissipate large amounts of heat (cooling) and subsequently reinsert it (heating). These heat flows to and from the heat reservoir 1, in conjunction with direct temporary storage, significantly reduce the energy required for operation, resulting in a recuperation effect. In addition to energy savings, the entire arrangement can also be significantly reduced in size and made very compact. Furthermore, the disclosed invention reduces the thermal material load on all components, particularly the Peltier elements 7.
  • the service life is also increased when the compact precision ThermoCycler is integrated into a microscopic measuring instrument enclosed by a housing, which is known to react sensitively to temperature fluctuations.
  • the negative impacts on the working environment caused by waste heat and fan noise are well-known disturbances.
  • Heat reservoir 1 can be easily adjusted to an optimized temperature.
  • the optimal temperature e.g., 40°C
  • the effect of recuperation is particularly effective with optimal temperature control, i.e., up to the extent limited by the efficiency of the Peltier elements 7 during cooling.
  • a further significant advantage is that the power loss peaks that occur during cooling can be quickly dissipated into a metallic (for example made of silver, copper or aluminum) heat reservoir 1.
  • a further increase in heat storage capacity can be achieved by using a second heat reservoir 5 consisting of PCM material (phase change material).
  • PCM material phase change material
  • the metallic heat reservoir 1 quickly absorbs, in particular, the short-term power peaks, while the second PCM heat reservoir 5 temporarily stores relatively larger amounts of heat. This results in an overall better power-to-mass ratio, since the PCM material can absorb and release significantly more heat energy than metallic versions in the relevant temperature range.
  • the PCM material can be selected according to the optimal required heat reservoir temperature. To dissipate sufficient energy from the first heat reservoir 1 despite the slower heat storage in the second heat reservoir 5, the contact surface between the two reservoirs is increased by extending metal pins or fins of the first heat reservoir 1 deep into the PCM.
  • the metallic first heat reservoir 1 significantly determines the speed and effectiveness of the overall arrangement.
  • ThermoCycler includes the guide for the movable stage adapter 8, fastening elements, and the insulation between the Temperature zones 9 and several cavity strips 10.
  • thermal insulation can be arranged in the direction of the xyz object stage 12 so that, for example, a microscope is not heated.
  • the compact design and small dimensions allow for easy use in a variety of commercially available microscopes.

  • the compact precision ThermoCycler itself with appropriate measurement technology based on optical or electrical sensors. This measurement technology can be fully integrated, but is preferably connected via the microscope adapter as an independent reader module.
  • thermocyclic temperature control of reaction chambers allows a range of investigations on microscopic structures with simultaneous temperature control of the reaction chamber and thus also of the microstructures, which were previously not possible or at least not optimally possible.
  • fluorescence-coupled, thermocyclic or isothermal reactions such as multiplex real-time PCR or LAMP on biochips and bead assays, e.g. for the detection of various microorganisms or molecular tumor markers.
  • multiplex detection methods can also be combined with melting curve analyses to measure the binding strength of analytes such as the avidity of antibodies or to analyze single nucleotide polymorphisms (SNPs) in genes.
  • SNPs single nucleotide polymorphisms
  • step gradients or linear gradients are used with simultaneous stepwise or continuous analysis of the reaction.
  • a thermal reaction control By means of the disclosed method of coupling eversen or, preferably, inverse multicolor fluorescence microscopy with a thermal reaction control, cells, tissues, or biomolecules can be examined individually or combined in multiplex systems down to single-molecule resolution, i.e., the optical resolution of nanostructures. It is also possible to use the microscope optics in such a way that the aforementioned reactions can optionally be measured summatively without optical resolution of the micro- and nanostructures in the reaction space.
  • the integration of a sufficient number of microscopically viewable cavity strips 10 in a ThermoCycler can now be implemented for the first time without exceeding the standard dimensions of the microtest plate specimen holder of a microscope.
  • the 96-well format commonly used in routine laboratories is achieved.
  • Each of these cavity strips 10 can be individually controlled as a temperature zone.
  • Fig. 1 shows the exploded view of a compact precision ThermoCycler with a heat reservoir 1.
  • the cooling block 2 serves to dissipate excess heat loss. It is advantageously constructed as a unit consisting of a square aluminum profile with an integrated fan. To ensure that the first heat reservoir 1 quickly reaches the optimal operating temperature, the first heat reservoir 1 is connected to a demand heater 15.
  • one or more heat reservoirs made of PCM material 5 can be connected downstream of the fast-acting metallic heat reservoir 1.
  • the combination of a first heat reservoir 1 and at least one second heat reservoir 5 results in a highly effective, complex heat reservoir that combines the properties of high volume and weight efficiency, high thermal energy storage capacity, and rapid heat power absorption.
  • the relatively slow charging and discharging rate of the PCM heat reservoir 5 can be significantly increased by increasing the contact surface between the two reservoirs. This effect is advantageously achieved by arranging metal pins or fins on the first heat reservoir 1, which are designed to extend deep into the PCM heat reservoir 5. At the same time, this eliminates an undesirable heat transfer surface compared to a more obvious separate design of the heat reservoirs.
  • the cavity strips 10 contain conical openings (cavities) for accommodating sample vessels, such as Nucleolink modules (Nunc).
  • the angle of the cones e.g., 17.2° is selected so that the sample vessels are held in the cavity strip 10 in a self-locking and force-fitting manner during cyclic temperature changes due to friction. This ensures good, stable heat transfer between the samples via the sample vessels and the cavity strips 10.
  • Peltier elements 7 are used, in accordance with the gold standard of classical PCR technology.
  • the characteristic curve of the temperature in the Fig. 2 demonstrates the outstanding precision of the temperature control achieved without any significant overshoots in the temperature curves.
  • additional heat pipes 6 are embedded inside the cavity strips 10. This effectively increases the speed of the temperature transitions by an order of magnitude.
  • the Peltier elements 7 positioned at both ends of the heat pipes 6 can, if necessary, significantly increase the heat transfer capacity of the heat pipes 6 by up to four times compared to the use of a heat pipe 6 with a single-sided temperature control. This is done by introducing a heat flow into the cavity strips 10 from both sides and additionally halving the path of the heat flow.
  • temperature sensors 11 are arranged, which are suitably attached to a temperature zone at least in each cavity strip 10 and to the heat reservoir 1.
  • the energy supply to the Peltier elements 7 is controlled by an attached energy supply and control block 3.
  • the corresponding algorithms are implemented in the form of digital control by means of a microcomputer 4 integrated into the energy supply and control block 3.
  • the ThermoCycler according to the invention can be mounted directly on an xyz stage 12 of a conventional fluorescence microscope (in Figure 1 only schematically indicated).
  • a feasible dead weight of the inventive ThermoCycler of only approximately 1.5 kg state-of-the-art xyz stages of standard microscopes with high acceleration rates and thus very short travel times can be used.
  • Fig. 1 shows the preferred viewing direction of a microscope 13, i.e. the viewing direction of the microscope 13 is from below onto the bottom of the sample vessels and thus through them onto the samples.
  • This viewing direction offers the advantage that imaging particles of the samples (e.g. beads during the evaluation of bead assays, see Rödiger et al. 2012, Rödiger et al. 2017, Hanschmann et al. 2021), which collect and settle at the bottom of the sample containers, thus generally keeping the distance of the particles to the microscope constant within narrow limits.
  • This fulfills an essential prerequisite for quantitative, high-quality PCR analysis by providing sharp, high-contrast images in real time, from which the data for the evaluation of, for example, PCR or melting curve analyses is ultimately extracted.
  • optical arrangement described here primarily refers to inverted microscopes. In principle, however, the solution according to the invention can also be used with upright microscopes, if this is advantageous, for example, for in situ studies on living cells. Imaging can also be omitted entirely or optionally during analysis.
  • the biochips can be placed on the upper support surface of the cavity bars 10. Depending on the scale, up to 96 Observation points can be used. Further possible configurations of this approach include the placement of suitable slides and the arrangement of biochips and slides on the underside of the cavity strips 10 using a simple, suitable pressure or suction option.
  • Fig. 2 shows in the temperature range from 28° C to 32° C (lower solid line) the only very slight fluctuations in the temperature of the heat reservoir 1 with a compact precision ThermoCycler according to the invention as a result of the absorption or release of heat energy during heating or cooling.
