I-III-VI QDs (CuInS2/ZnS or AgInS2/ZnS core/shell structures) possess low toxicity, and are a logical replacement for cadmium-based QDs for biomedical applications. Our synthesis of I-III-VI QDs is based on thermal decomposition of less toxic precursors and can be easily scaled up for mass production for sustainable and reliable imaging and sensing experiments. Through nonstoichiometric composition adjustment, we synthesized I-III-VI QDs with reliable and controllable optical properties, including high QYs and tunable photoluminescence. We also developed new zwitterionic amphiphiles and applied them to encapsulate I-III-VI QDs to achieve colloidal stability in proteinaceous solutions with wide pH/ionic ranges, low non-specific binding, and easily bio-conjugation. On the basis of these developments, we applied our I-III-VI QDs in cellular imaging to to specifically target human brain tumor cells.

The colloidal silver solution was successfully prepared in dielectric fluid by using electrical spark discharge (ESD) without any surfactants. It does not require the toxic chemical agents in the process, which may affect the effectiveness of nanosilver colloid as an antibacterial agent. Nanocolloidal silver produced by ESD is characterized as low cost, zero environmental pollution, continuous, and rapid mass production process. In order to test the effect of antibioactivity, nanosilver dough was tested; the silver nanofluid was prepared by ESD machine, made into dough at different concentrations, and fermented for three hours in order to observe changes in the diameter of the dough. The results showed that the effect of effectiveness of nanosilver at the concentration of 100 ppm was weak, whereas the effect of 60 ppm silver ion (100 ppm AgNO3) was significant, as the dissociation rate of silver ion concentration correlates to the antibioactivity.

Severe acute respiratory syndrome [SARS]-CoV-2, which is the causative agent of Coronavirus Disease 2019 [COVID-19] disease, has engulfed more than 2.4 million people and still counting. As this pandemic is at its peak and is responsible for more than 100 million infected people worldwide, there is an urgent need to develop an effective vaccine to stop the COVID-19 disease. More than 220 vaccine candidates are in the pre-development stage while 15 candidates are in the developmental stage, from which Pfizer/BioNTech, Moderna, and some other vaccines have received approval by some countries for emergency use only. Fever, tiredness, headache, joint pain, swelling at the injection site and some other common effects have been found by using these vaccines. Efficacy, rapid mass production, and long-term immunity as well as acceptance of vaccination by society are the main challenges in developing a safe vaccine against COVID-19 despite the fact that some vaccines have over 90% efficiency against COVID-19 and are useful in developing immunity as well.
