Uranyl acetate (UA) is one of the heavy metals used to stain tissue in sample preparation for transmission electron microscopy (TEM). It gives excellent contrast to ultrastructure morphology. Unfortunately, UA is very toxic and has proven to be a carcinogen and radioactive reagent. Meanwhile, UA-Zero is a UA replacement with improved staining property has shown better for staining due to its safety profile and environmental-friendly properties....
Possible Effect of Nano Characterization of COVID-19 on Infection and Causing Disease
Article Type: Original Article | First Published: February 23, 2023
In this article, based on analysis of chemical composition and morphology structure of the New Coronavirus Disease-19 (COVID-19), that the COVID-19 belongs a kind protein nanoparticle virus with spherical complex structure has been explained. So, the COVID-19 possesses characteristics of ultra-small size, large specific surface, both hydrophilicity and lipophilicity, that just as all of the nanoparticles. It leads to the COVID-19 producing fast spread speed, large spread range and strong infecti...
