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.

An overview of the BNT162b2 COVID-19 vaccine by Pfizer-BioNTech

In a study published in the journal Drugs, a researcher tackled the approval of Pfizer-BioNTech’s COVID-19 vaccine, which has now been used in many countries.

Optimized SARS-CoV-2 vaccine candidate could be less reactogenic, say researchers

A new study, released as a preprint on the bioRxiv* server, reports an optimized coronavirus disease 2019 (COVID-19) vaccine candidate, which, claim the researchers, may be less likely to produce reactions like fevers. It may also have increased protective potential against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes COVID-19.

Self-assembling nanoparticles an effective vaccine candidate for SARS-CoV-2

The currently developed vaccines against SARS-CoV-2 include the RBD in their immunogen. With a similar objective, a new study developed an RBD protein-based vaccine candidate against the SARS-CoV-2, using self-assembling Helicobacter pylori-bullfrog ferritin nanoparticles as an antigen delivery system. The study is published recently in the journal mBio (by the American Society of Microbiology).

Data from Israel’s vaccination program suggests Pizer-BioNTech COVID-19 vaccine induces strong host antibody response

A team of scientists from Israel has recently evaluated the efficacy of an mRNA-based coronavirus disease 2019 (COVID-19) vaccine, BNT162b2, in inducing host humoral immune response. The findings reveal that the vaccine is capable of inducing strong anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody response and that the response varies significantly with age. The study is currently available on the medRxiv* preprint server.

Results from phase 2 trial of Novavax recombinant nanoparticle SARS-CoV-2 vaccine

Novavax, Inc., the American vaccine development company, has been developing a recombinant protein nanoparticle COVID-19 vaccine currently termed NVX-CoV2373. The full-length spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is created in a baculovirus vector, which is then inserted into a lipid nanoparticle around 50 nm in diameter.

Novel single-particle digital assay using plasmonic nanobubbles

An interdisciplinary team from the University of Texas applied DIAMOND to the respiratory syncytial virus (RSV) diagnostics and demonstrated that DIAMOND is 150 times more sensitive than commercial lateral flow assays. They found that the measurements are completed within 2 minutes. The results of this study are published on the medRxiv* preprint server.

After billions of dollars and dozens of wartime declarations, why are vaccines still in short supply?

The U.S. government has invested billions of dollars in manufacturing, used a wartime act dozens of times to boost supplies and yet there's still not enough covid vaccine on the way to meet demand — or even the government's own goals for national immunization.

Gold nanoparticles investigated as part of in vitro tool for SARS-CoV-2 drug screening

Scientists have measured the interaction of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein with nano-gold colloids. These nanoparticles functionalized with the S protein have different spectroscopic signals allowing for new information about the protein to be extracted.
