CoViD-19 disinfectant tester by using a defect layered 1D quaternary photonic band gap structure

In this note, a CoViD-19 disinfectant tester is proposed by using a defect layered 1D Quaternary photonic band gap structure (QPBGS). This disinfectant tester can detect adulteration in CoViD-19 hand disinfectants or sanitizers. The disinfectant to be tested can be poured into the empty defect layer of the defect layered 1D QPBGS. The spectra of the adulterated and unadulterated sanitizer filled structures can be compared to detect adulteration.
