Cyclic Olefin Copolymer\nValues for the density (ρCOC = 1020 kg m−3), specific heat (cCOC, see Table A2), and thermal conductivity (κCOC,23°C = 0.17 W m−1 K−1 and κCOC,320°C = 0.24 W m−1 K−1, linear fit in between these point) of TOPAS 6017 COC are obtained via TOPAS Advanced Polymers (TOPAS Advanced Polymers, Farmington Hills, MI, USA). The heat capacity at constant pressure (CP,COC) is calculated assuming a homogeneous body of mass m, via Equation (A5), where COMSOL interpolated linearly in between the points. (A5) CP,COC=cCOC×m\nTable A2 The specific heat of TOPAS 6017 COC.\nT c T c\n[°C] [W m−1 K−1] [°C] [W m−1 K−1]\n30 1333 180 2298\n70 1538 210 2412\n110 1754 250 2539\n150 1968 290 2645\n160 2047 330 2758 Convective heat loss to the air is also taken into account with Equation (A6), which is often used in simulations [56]. (A6) h=10Wm−2K−1\n\nAppendix C. TCR Measurements\nThe two subsections below show two effects on the TCR measurements, i.e., the effect of thermal annealing during the first temperature cycle and the effect of aging.\n\nAppendix C.1. Thermal Annealing\nThe graph below is an example of the measured thermal annealing of a metal layer on COC. Here, only the graph for evaporated Au is shown, but all except evaporated Pt show this behavior. Evaporated Pt had some contaminants in the metal track. This is most probably caused by the shadow mask.\nFigure A2 Thermal annealing of an evaporated 100 nm Au layer.\n\nAppendix C.2. Aging\nThe layer analyzed in Figure A2 is stored for two weeks in ambient conditions and the TCR is analyzed again. From the graph it is visible that the aging has some effect on the TCR of the metal layer.\nFigure A3 The effect of two weeks aging in ambient conditions on a 100 nm Au layer. The TCR of the as deposited layer is 0.00161 K−1 and the TCR of the two week old layer is 0.00224 K−1.\n\nAppendix D. MDA Reaction Mixture\nThe reaction mixture for the on-chip MDA reaction consisted of the following.\nTable A3 On-chip MDA reaction mixtures.\nSample Reaction Buffer Sample Buffer DNA MilliQ DI Water EG Enzyme\n[μL] [μL] [μL] [μL] [μL] [μL]\nTube with DNA 9 9 1 - 4 1\nTube NTC 9 9 - 1 4 1\nChip with DNA 9 9 1 - 4 1\nChip NTC 9 9 - 1 4 1\n\nAppendix E. Background Signal Fluorescence Measurements\nAll fluorescence measurements in the Horiba Scientific FluoroMax+ spectrofluorometer are normalized by subtracting the background signal. This background signal is measured using the mixture in Table A4.\nTable A4 Mixture used for background signal measurement.\nSample Reaction Buffer Sample Buffer DNA MilliQ DI Water EG Enzyme\n[μL] [μL] [μL] [μL] [μL] [μL]\nBackground 9 9 1 1 4 -\nFigure A4 The background signal of the mixture in Table A4."}

Cyclic Olefin Copolymer\nValues for the density (ρCOC = 1020 kg m−3), specific heat (cCOC, see Table A2), and thermal conductivity (κCOC,23°C = 0.17 W m−1 K−1 and κCOC,320°C = 0.24 W m−1 K−1, linear fit in between these point) of TOPAS 6017 COC are obtained via TOPAS Advanced Polymers (TOPAS Advanced Polymers, Farmington Hills, MI, USA). The heat capacity at constant pressure (CP,COC) is calculated assuming a homogeneous body of mass m, via Equation (A5), where COMSOL interpolated linearly in between the points.

(A6) h=10Wm−2K−1\n\nAppendix C. TCR Measurements\nThe two subsections below show two effects on the TCR measurements, i.e., the effect of thermal annealing during the first temperature cycle and the effect of aging.\n\nAppendix C.1. Thermal Annealing\nThe graph below is an example of the measured thermal annealing of a metal layer on COC. Here, only the graph for evaporated Au is shown, but all except evaporated Pt show this behavior. Evaporated Pt had some contaminants in the metal track. This is most probably caused by the shadow mask.\nFigure A2 Thermal annealing of an evaporated 100 nm Au layer.\n\nAppendix C.2. Aging\nThe layer analyzed in Figure A2 is stored for two weeks in ambient conditions and the TCR is analyzed again. From the graph it is visible that the aging has some effect on the TCR of the metal layer.\nFigure A3 The effect of two weeks aging in ambient conditions on a 100 nm Au layer. The TCR of the as deposited layer is 0.00161 K−1 and the TCR of the two week old layer is 0.00224 K−1.\n\nAppendix D. MDA Reaction Mixture\nThe reaction mixture for the on-chip MDA reaction consisted of the following.\nTable A3 On-chip MDA reaction mixtures.\nSample Reaction Buffer Sample Buffer DNA MilliQ DI Water EG Enzyme\n[μL] [μL] [μL] [μL] [μL] [μL]\nTube with DNA 9 9 1 - 4 1\nTube NTC 9 9 - 1 4 1\nChip with DNA 9 9 1 - 4 1\nChip NTC 9 9 - 1 4 1\n\nAppendix E. Background Signal Fluorescence Measurements\nAll fluorescence measurements in the Horiba Scientific FluoroMax+ spectrofluorometer are normalized by subtracting the background signal. This background signal is measured using the mixture in Table A4.\nTable A4 Mixture used for background signal measurement.\nSample Reaction Buffer Sample Buffer DNA MilliQ DI Water EG Enzyme\n[μL] [μL] [μL] [μL] [μL] [μL]\nBackground 9 9 1 1 4 -\nFigure A4 The background signal of the mixture in Table A4."}

Equations and Values Used in the COMSOL Multiphysics Study\n\nAppendix B.1. Water\nFor H2O, the build-in temperature-dependent equations for the density (ρH2O, see equations in Equation (A1)), heat capacity at constant pressure (CP,H2O, see equations in Equation (A2)), and thermal conductivity (κH2O, see equations in Equation (A3)) are used. The ratio (γH2O) of the specific heats at constant pressure (CP,H2O) and constant volume (CV,H2O) is calculated manually according to the table from the Engineering Toolbox website [81] and Equation (A4). The values for γH2O are listed in Table A1.

Equations and Values Used in the COMSOL Multiphysics Study\n\nAppendix B.1. Water\nFor H2O, the build-in temperature-dependent equations for the density (ρH2O, see equations in Equation (A1)), heat capacity at constant pressure (CP,H2O, see equations in Equation (A2)), and thermal conductivity (κH2O, see equations in Equation (A3)) are used. The ratio (γH2O) of the specific heats at constant pressure (CP,H2O) and constant volume (CV,H2O) is calculated manually according to the table from the Engineering Toolbox website [81] and Equation (A4). The values for γH2O are listed in Table A1.

Cyclic Olefin Copolymer\nValues for the density (ρCOC = 1020 kg m−3), specific heat (cCOC, see Table A2), and thermal conductivity (κCOC,23°C = 0.17 W m−1 K−1 and κCOC,320°C = 0.24 W m−1 K−1, linear fit in between these point) of TOPAS 6017 COC are obtained via TOPAS Advanced Polymers (TOPAS Advanced Polymers, Farmington Hills, MI, USA). The heat capacity at constant pressure (CP,COC) is calculated assuming a homogeneous body of mass m, via Equation (A5), where COMSOL interpolated linearly in between the points.

TCR Measurements\nThe two subsections below show two effects on the TCR measurements, i.e., the effect of thermal annealing during the first temperature cycle and the effect of aging.\n\nAppendix C.1. Thermal Annealing\nThe graph below is an example of the measured thermal annealing of a metal layer on COC. Here, only the graph for evaporated Au is shown, but all except evaporated Pt show this behavior. Evaporated Pt had some contaminants in the metal track. This is most probably caused by the shadow mask.\nFigure A2 Thermal annealing of an evaporated 100 nm Au layer.\n\nAppendix C.2. Aging\nThe layer analyzed in Figure A2 is stored for two weeks in ambient conditions and the TCR is analyzed again. From the graph it is visible that the aging has some effect on the TCR of the metal layer.\nFigure A3 The effect of two weeks aging in ambient conditions on a 100 nm Au layer. The TCR of the as deposited layer is 0.00161 K−1 and the TCR of the two week old layer is 0.00224 K−1.\n\nAppendix D. MDA Reaction Mixture\nThe reaction mixture for the on-chip MDA reaction consisted of the following.\nTable A3 On-chip MDA reaction mixtures.\nSample Reaction Buffer Sample Buffer DNA MilliQ DI Water EG Enzyme\n[μL] [μL] [μL] [μL] [μL] [μL]\nTube with DNA 9 9 1 - 4 1\nTube NTC 9 9 - 1 4 1\nChip with DNA 9 9 1 - 4 1\nChip NTC 9 9 - 1 4 1\n\nAppendix E.
