Indeed, coronaviruses are known to make use of lipids as target cell entry receptors, and as factors in viral replication complex synthesis and formation. Moreover, a recent study showed that small molecules such as sterols and cyclo- dextrin may disrupt the lipid-dependent attachment of the virus to host cells, and as such may reduce the infectivity of the SARS-CoV-2.6 One possible aspect of these observations that has yet to be explored in detail is what role arthropods that have been associated with human skin infestation, such as Demodecidae or Pyemotidae species, play in viral transmission. These arthropods share a common polymer, chitin, as an integral part of their exoskeletons. Chitin and chitosan, the enzymatic product of chitin produced through bacterial degrada- tion, have unique properties that have stimulated interest in their pos- sible biomedical applications. They are both non-toxic, biodegradable, biocompatible, and can form films on the skin, and these unique prop- er

Quantum dots can be manufactured by a number of processes from colloidal synthesis to chemical vapour deposition (CVD). The cheapest and simplest method is benchtop colloidal synthesis. Electrochemical techniques and CVD can be used to create ordered arrays of quantum dots on a substrate material.15 Dec 2006

Crystals grow when the solution becomes supersaturated, meaning that there is too much salt dissolved in the water. The extra salt (or other material) takes the form of crystals. To get a supersaturated solution you can either cool down the solution or let some of the water evaporate.
