Controlling strong electromagnetic fields on nanoparticles is the key to triggering targeted molecular reactions on their surfaces. Such control over strong fields is achieved via laser light. Although laser-induced formation and breaking of molecular bonds on nanoparticle surfaces have been observed in the past, nanoscopic optical control of surface reactions has not yet been [...]
A paper recently published in the journal Nature Communications demonstrated an effective method to realize on-chip nanophotonic topological rainbow devices using the concept of synthetic dimensions. Importance of Synthetic Dimensions for the Construction of Topological Nanophotonics Device Topological photonics witnessed significant advancements in the last few years. Due to topological protection, photonic devices have become more [...]
In a study available in the journal Materials Today: Proceedings, silver nanoparticles (Ag NPs) were fabricated using a green method using Citrus X sinensis. Methylthioninium Chloride (MB) Dyes Threatening the Environment Dye and sewage drainage into waterways by factories is a significant ecological issue. The dye produced by large textile factories and other businesses has major [...]
Scientists are studying whether long COVID could be linked to viral fragments found in the body months after initial infection. In the chaos of the first months of the coronavirus pandemic, oncologist and geneticist Ami Bhatt was intrigued by widespread reports of vomiting and diarrhoea in people infected with SARS-CoV-2. “At that time, this [...]
Public health experts are divided over how many people are getting long COVID-19, a potentially debilitating condition that comes after a patient has recovered from the coronavirus. Ill effects from the condition can include fatigue, pain, neurological issues and even changes in mental health. Initially, public health officials believed that only a small minority [...]
Well over two years into the pandemic, hundreds of thousands of COVID cases continue to be recorded around the world every day. With the rise of new variants, the symptoms of COVID have also evolved. Initially, the NHS regarded a fever, cough, and loss or change in sense of smell or taste as the main symptoms which [...]
Nanoparticles are everywhere. They are in our body as protein aggregates, lipid vesicles, or viruses. They are in our drinking water in the form of impurities. They are in the air we breath as pollutants. At the same time, many drugs are based on the delivery of nanoparticles, including the vaccines we have been [...]
Drug resistance is a common phenomenon, with drugs becoming less and less effective as their usage increases. To address this issue, a novel technique employing conjugated polymer-based nanoparticles is presented in the study published in the journal ACS Applied Materials and Interfaces. What is TRAIL? TNF-related apoptosis-inducing ligand (TRAIL), a part of the TNF superfamily, [...]
Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at high resolution in a living organism. How can a blood clot be removed from the brain without any major surgical [...]
Scientists have recently developed multifunctional hexagonal NaxWO3 nanocrystals that can serve as microwave sensitizers to kill cancer cells as well as improve the overall chemodynamic therapy (CDT). This study is available as a pre-proof in Chemical Engineering Journal. Technologies Associated with Clinical Management of Tumors Some of the thermal ablation technologies, such as radiofrequency ablation (RFA) and microwave [...]
