https://www.selleckchem.com/products/pf-06952229.html Emerging molecular diagnosis requires ultrafast polymerase chain reaction (PCR) on chip for rapid precise detection of infectious diseases in the point-of-care test. Here, we report nanoplasmonic on-chip PCR for rapid precision molecular diagnostics. The nanoplasmonic pillar arrays (NPA) comprise gold nanoislands on the top and sidewall of large-scale glass nanopillar arrays. The nanoplasmonic pillars enhance light absorption of a white light-emitting diode (LED) over the whole visible range due to strong electromagnetic hotspots between the nanoislands. As a result, they effectively induce photothermal heating for ultrafast PCR thermal cycling. The temperature profile of NPA exhibits 30 cycles between 98 and 60 °C for a total of 3 min and 30 s during the cyclic excitation of white LED light. The experimental results also demonstrate the rapid DNA amplification of both 0.1 ng μL-1 of λ-DNA in 20 thermal cycles and 0.1 ng μL-1 of complementary DNA of Middle East respiratory syndrome coronavirus in 30 thermal cycles using a conventional PCR volume of 15 μL. This nanoplasmonic PCR technique provides a new opportunity for rapid precision molecular diagnostics.The aprotic lithium-oxygen (Li-O2) battery has triggered tremendous efforts for advanced energy storage due to the high energy density. However, realizing toroid-like Li2O2 deposition in low-donor-number (DN) solvents is still the intractable obstruction. Herein, a heterostructured NiS2/ZnIn2S4 is elaborately developed and investigated as a promising catalyst to regulate the Li2O2 deposition in low-DN solvents. The as-developed NiS2/ZnIn2S4 promotes interfacial electron transfer, regulates the adsorption energy of the reaction intermediates, and accelerates O-O bond cleavage, which are convincingly evidenced experimentally and theoretically. As a result, the toroid-like Li2O2 product is achieved in a Li-O2 battery with low-DN solvents via the solvation-mediated
