Lawrence Livermore National Laboratory (LLNL) scientists are scaling up the production of vertically aligned single-walled carbon nanotubes (SWCNT) that could revolutionize diverse commercial products ranging from rechargeable batteries, automotive parts and sporting goods to boat hulls and water filters. The research appears in the journal Carbon ("Synthesis of wafer-scale SWCNT forests with remarkably invariant structural properties in a [...]

Researchers at Karolinska Institutet have in a new study used cellular reprogramming to create human three-dimensional brain models and infected these models with SARS-CoV-2. In infected models, the brain immune cells excessively eliminated synapses and acquired a gene expression pattern mimicking what has been observed in neurodegenerative disorders. The findings could help to identify [...]

Together with colleagues, a group of scientists from Immanuel Kant Baltic Federal University synthesized nanostructures of gold and iron oxides that have improved magnetic and optical properties because of their unique star shape. The particles obtained are safe for healthy human cells and can be used in tumor therapy. The results of the [...]

Nanoplastics derived from plastic waste are increasingly accumulating in agricultural farmlands. The absorption and deposition of plastic particles by crops pollute the food supply and pose unanticipated health concerns to human beings. However, the effects of nanoplastics on crop grains cultivated in polluted soil remain relatively unknown. A recent study published in the journal Advanced Science tackles [...]

Scientists from Trinity College Dublin believe our brains could use quantum computation. Their discovery comes after they adapted an idea developed to prove the existence of quantum gravity to explore the human brain and its workings. The brain functions measured were also correlated to short-term memory performance and conscious awareness, suggesting quantum processes are also [...]

Scientists at RMIT University say their new research advances the potential of nanomedicine to cure conditions that are currently incurable, such as dementia and motor neurone disease. Their work explores how nanoparticles would interact with cells in humans and provides fundamental knowledge to help improve nanomedicine and develop the next generation of personalised biomedical [...]

A study led by an Oregon State University pharmaceutical sciences researcher has produced a proof of principle for a new “universal” means of treating COVID-19. Gaurav Sahay and collaborators at OSU and the Texas Biomedical Research Institute demonstrated in a mouse model that it’s possible to prompt the production of a protein that can [...]

Electronic and photonic devices have unique functionalities for converting chemical and biological processes into electrical or optical signals to detect, identify, and monitor these processes. Integrating nanotechnology concepts has led to various innovative optoelectronic designs that empower next-generation devices. Deoxyribonucleic acid (DNA) is the molecule that stores and transmits genetic information in biological systems. [...]

The US Food and Drug Administration authorised the use of versions of Moderna and Pfizer/BioNTech covid-19 vaccines that target both the original virus and two omicron subvariants. The US Food and Drug Administration (FDA) granted emergency use authorisation on 31 August to covid-19 vaccines that target two different coronavirus variants. These updated “bivalent” vaccine [...]

Nanoparticles can be used as powerful vehicles to administer vaccines and prevent serious illness, as with the treatment of COVID-19 and to deliver chemotherapeutic drugs to cancer cells with goal of eradicating the cancer cells and leaving the healthy cells unharmed. For cancer patients, this has the potential to reduce severe side effects that [...]
