Anti-Microbial Nanotechnology: Interview with Adrian Fellows, Head of R&D at AGA Nanotech

AGA Nanotech, a medtech company based in the UK, has developed nanotechnologies aimed at overcoming antimicrobial resistance, with a view to offering an alternative to conventional antibiotics. The company has collaborated with researchers from University College London to create poly(lactic-co-glycolic acid) (PLGA) nanoparticles that can deliver h (Read more...)

Sugar-Coated Nanosheets Can Selectively Bind Pathogens

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have developed sugar-coated ultrathin self-assembling nanosheets that can selectively bind to pathogens, and which have potential to serve as a diagnostic technology or a way to inactivate pathogens. The researchers developed the structures using bioinspired (Read more...)

Bacteria Coerced to 3D Print Nanocellulose Implants

In a quest to make more realistic, safer, and personalizable tissue replacement implants, bacterial cellulose nanofibers are being looked on as a viable material. They are naturally biocompatible, biodegradable, withstand heat well, and have physical properties similar to many of our tissues, when composed into larger objects. Bacterial cellulose n (Read more...)

Nanofiber Dressings Speed Up Healing of Serious Wounds

Researchers at Harvard University have come up with two new wound dressings that promote healing without relying on growth factors, cells, or even artificial scaffolds. Instead, natural proteins that are found in soy and human fetus cells are made to speed up the body’s natural healing processes, including performing tricks that only fetal ti (Read more...)

Artificial Photoreceptors Return Vision to Blind Mice

Blindness in many people is caused by diseased rod and cone cells within the retina that are responsible for turning light into electric signals. If these photoreceptor cells don’t function correctly, even an otherwise perfectly healthy eye won’t produce quality vision. There are technologies out there that bypass photoreceptors entirel (Read more...)

Magnetic Nanoparticles to Stop Internal Bleeding

Researchers from ITMO University in St. Petersburg, Russia have developed magnetic nanoparticles to control internal bleeding, which can be localized at a bleeding site in the body using external magnetic fields. Internal bleeding is a medical emergency, and researchers are working to develop more effective therapies that are targeted at the bleedi (Read more...)

Nanoparticle Material Melts Away to Reveal Drug Cargo

At the Technion-Israel Institute of Technology, researchers have developed a new set of materials designed to deliver drugs inside the body and melt away when illuminated with light. The materials are made of a polymer seeded with nano-sized gold shell nanoparticles. When light from a near-infrared (NIR) laser is applied to the material, it me (Read more...)

Machine Learning for Building Personalized Cancer Nanomedicines: Interview with Dr. Daniel Heller

Researchers at the Sloan Kettering Institute and the Weill Cornell Graduate School of Medical Sciences in New York have developed a machine learning approach to design personalized nanoparticle therapies for cancer. Personalized cancer therapies aim to provide a treatment that is tailored to the genetic makeup of a patient’s tumor. They can s (Read more...)
