Novel approach to enhance antifungal properties via formation of wavy and Sharp microstructures composed of metal oxide nanoparticles and Cdots by Satya Pal Singh, Himanshi Yadav, Himanshi Chauhan, Vivek Hada, Kumari Neha Singh

“…The microtiter plates were first coated with 2, 5-dimercapto-1,3,4-thiadiazole (DMcT) dissolved in methanol (1 gm/mL) and were then dried and coated with NPs and C-dots using their suspensions in deionised water with three different concentrations. The evolution of spinodal wave-like structures, as reported in our case of evaporating thin films, appears to leave behind spiky and periodic wavy blades and needle-like nano-microstructures composed of NPs and Cdots. …”
