Nanodiamonds may be tiny, but they can help with one of the biggest problems facing humanity today: Climate change. Hydrogen, a clean-burning fuel, leaves nothing but water when consumed. Many countries view hydrogen as a way to a zero-carbon future, but switching to a hydrogen economy requires its production to be much more affordable [...]
A bottom-up approach to produce copper oxide (CuO) nanoparticles on hydrophilic graphene oxide (GO) nanosheets has been employed in the latest research published in Journal of Material Science: Materials in Medicine. The CuO/GO nanocomposite was created by combining two different predecessors, copper nitrate and citric acid, with occasional mixing of GO solutions. Importance of Copper [...]
Led by the University of Oxford, a team of UK-based researchers have today reported results of the largest ever study to compare the risks of cardiovascular events, such as myocarditis, pericarditis, and cardiac arrhythmia, between different vaccines and COVID-19 infection, and the first to investigate the association between cardiac events and the Oxford-AstraZeneca vaccine. [...]
Researchers at Sandia have created a platform for discovering, designing and engineering novel antibody countermeasures for emerging viruses. This new process of screening for nanobodies that "neutralize" or disable the virus represents a faster, more effective approach to developing nanobody therapies that prevent or treat viral infection. Traditionally used to treat a variety of [...]
Findings Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have identified rare, naturally occurring T cells that are capable of targeting a protein found in SARS-CoV-2 and a range of other coronaviruses. The findings suggest that a component of this protein, called viral polymerase, could potentially be [...]
Nanoparticles initially designed as biological markers are entering their first therapeutic trial as a treatment for patients with advanced, recurrent or refractory cancers. From the beginning, these "Cornell dots"—silica-encased fluorescent nanoparticles, developed in the lab of Ulrich Wiesner, professor of engineering—were seen as having great potential as biological markers. The technology has been refined [...]
Researchers at the University of British Columbia have invented a thin, flexible battery that can be tossed into a load of laundry and survive. The washable works when twisted and stretched to twice its normal length and could be a boon for the wearable electronics industry, which includes both smart clothes and smart accessories, [...]
n June 2021, Israel’s early lead in the world vaccination race seemed to be crumbling. Months earlier it had been the real-world laboratory that showed the effectiveness of vaccines in crushing COVID-19 outbreaks. But now a surge of the faster-moving Delta variant was taking hold, including among the double-jabbed. Data indicated that people vaccinated [...]
For more than three decades, biomedical nanomaterials have been successfully developed for the benefit of theranostics—a compound term referring to the diagnoses and treatment of tumors. The nanoparticles must reach the tumor site and its distinct microenvironment to target the treatment for the tumor. Recent studies show the physical properties of nanoparticles, especially their [...]
With nanotechnology we can understand, mimic, and modulate our immune system. For her Ph.D. research, Annelies Wauters studied how tiny nanocarriers can be used to control the immune system, and target and activate immune cells to fight cancer cells. Wauters defends her thesis on December 3rd. For the past two years, the COVID-19 pandemic [...]
