Fig. 1. Light-to-heat energy transfer process in ultrafast photonic PCR. (a) Basic steps in one PCR cycle - denaturation, annealing, and elongation. (b) Illustration of photonic heating with DNA molecules and nanoparticles (NPs) in PCR mix; I_i: incident light waves, I₀: reflected ray. (c) Scheme of the photonic excitation lightto- heat conversion in a NP (energy gap between ground state and excited state).
