In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Researchers develop rapid COVID-19 diagnostic test affordable for low-income families

A test that detects antibodies to the novel coronavirus in 10 minutes and costs only a fifth of the market average has been developed by researchers at the University of São Paulo's São Carlos Chemistry Institute and Brazilian startup Biolinker, with São Paulo Research Foundation - FAPESP's support.

Inhaled single dose vaccine creates antibodies and prevents infection in rhesus macaques

Now, a new preprint research paper describes a chimpanzee adenovirus-vectored vaccine that, when administered intranasally in rhesus macaques, led to a robust immune response and demonstrated protection against infection by the virus that causes COVID-19, namely, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The preprint is published on the bioRxiv server.
