Composite polymer particles adorned with gold nanoparticles could improve the accuracy of infectious disease testing. Original story from Tohoku University Purple circles with small protrusions on a black background.GNDP particles Credit: Hiroshi Yabu By harnessing the power of composite polymer particles adorned with gold nanoparticles, a group of researchers have delivered a more accurate means...
by National Institutes of Health Researchers were able to visualize biofilms in teeth treated with dextran-coated gold nanoparticles using photoacoustic imaging. Credit: Journal of Clinical Investigation (2023). DOI: 10.1172/JCI168485If left to their own devices, bacteria on our teeth or wounded skin can encase themselves in a slimy scaffolding, turning into what is called biofilm. These...
Northwestern University researchers have developed the first selective therapy to prevent allergic reactions, ranging in severity from itchy hives and watery eyes to trouble breathing and even death.A scanning electron microscope image of nanoparticles (colorized in purple) that have successfully entered a mast cell To develop the new therapy, researchers decorated nanoparticles with antibodies capable...
Researchers at UC San Diego have developed modular nanoparticles that can be customized to target biological entities such as tumors, viruses or toxins.The surfaces of the nanoparticles are engineered to host biological molecules, making it possible to tailor the nanoparticles for applications from targeted drug delivery to neutralizing biological agents. Live cell fluorescent visualization of...
By Paul McClure Researchers have created a nanoparticle decorated with antibodies that targets the cells responsible for allergic reactionsEvan A. Scott/Northwestern University Researchers have created a nanotherapy that selectively targets and shuts down the immune cells responsible for causing an allergic response in mice, preventing anaphylaxis. Able to be tailored to specific allergens, the novel nanomedicine...
By CONN HASTINGSMEDICINE, NANOMEDICINE, NEWS, ONCOLOGY, SURGERY Researchers at the Georgia Institute of Technology have developed a nanotechnological solution for lymphedema, a failure of the lymphatic system that results in uncomfortable and irreversible fluid retention. Previous research efforts have focused on trying to grow new lymphatic vessels, but these researchers have taken a different approach,...
Autoimmune disorders are among the most prevalent chronic diseases across the globe, affecting approximately 5-7% of the world’s population. Emerging treatments for autoimmune disorders focus on “adoptive cell therapies,” or those using cells from a patient’s own body to achieve immunosuppression. These therapeutic cells are recognized by the patient’s body as ‘self,’ therefore limiting side...
November 01, 2023 by William Weir Using nanoparticles administered directly into the cerebrospinal fluid (CSF), a research team has developed a treatment that may overcome significant challenges in treating a particularly deadly brain cancer. The researchers, led by professors Mark Saltzman, PhD, and Ranjit Bindra, MD, PhD, administered to mice with medulloblastoma a treatment that...
by Yale University Credit: Yale University A team of researchers has developed an inhalable vaccine that successfully protects against the COVID virus. It also opens the door to delivering other messenger RNA (mRNA) therapeutics for gene replacement therapy and other treatments in the lungs. Results of the study, led by Prof. Mark Saltzman, are published in Science...
Posted 2 days ago In collaboration with Astra Zeneca, new research from Cardiff University used artificial intelligence to create microscopic nanoparticles that can effectively transport medicines to target and treat diseased cells precisely. Pills, medications in hand – illustrative photo. Modern medications are increasingly associated with the use of treatment-delivering nanoparticles. Image credit: Kateryna Hliznitsova via...
