Nanoparticles with Long Afterglow for Life Sciences Research

Molecular-scale fluorescent markers are a staple of many branches of life sciences research. They get excited and emit a glow when illuminated with a laser, and so can be spotted and associated with cells and other biological things they’re attached to. A common problem with the fluorescent agents is that they lose their glow shortly [&hellip (Read more...)

Artificial Beta Cells Can Release Insulin On-Demand

Researchers from the University of North Carolina and North Carolina State University have developed artificial beta cells that can release insulin in response to rising glucose levels in the blood stream. The technology could be used to treat diabetes through subcutaneous injections of the cells into patients, or gradual delivery using a skin patc (Read more...)

Abionic Detects Your Allergies in Minutes

Abionic, a Swiss company, has received US Food and Drug Administration (FDA) registration for detecting allergies to cats, dogs, trees, and grasses. The firm’s nanotechnology-focused assay can yield results in as little as five minutes, with some tests taking up to 20 minutes, and uses just a single drop of blood (no this isn’t a [&hell (Read more...)

Tiny Nanopatch Shown Highly Effective Against Polio Virus

A new vaccine delivering “Nanopatch” has just been tested that may finally help put an end to polio. Developed by a scientist at Queensland University in Australia and commercialized by Vaxxas, a firm based in Sydney, the patch has microscopic needles projecting from its bottom that pass the vaccine directly to the antigen-presenting ce (Read more...)

Molecular Robots to Build Drug Molecules

Scientists in the UK have developed a microscopic molecular machine that can be used to assemble individual molecules. The technology could allow scientists to build drug molecules from scratch, as well as help with drug discovery. The molecular robots are only a millionth of a millimeter in size and each has a tiny robotic arm. […]

Acoustofluidics Pulls Exosomes from Whole Blood

Exosomes are tiny vesicles that are released by the body’s myriad of cells and that are found in blood, urine, and other bodily fluids. Their role within our bodies is still largely a mystery, but there’s already considerable evidence that they may be biomarkers of disease and indicators that certain processes are happening within the [ (Read more...)

Microneedle Patch Burns Fat Below Skin

Researchers in the US have developed a microneedle patch that can be applied to the skin and help to burn fat locally. The patch releases a drug that converts white fat to energy-burning brown fat, and could help to reduce “love handles”, and treat obesity and diabetes. Medgadget recently covered drug-loaded nanoparticles that (Read more...)

New Way to Deliver Chemo Agent Helps Reach Brain Tumors

While there are fairly effective medications that can kill brain tumors, getting them to their targets is so challenging that they’re often next to useless for cancers of the brain. Japanese scientists from Kawasaki Institute of Industrial Promotion, The University of Tokyo, and Tokyo Institute of Technology have developed a shell for epirubi (Read more...)

Quantum Dots Light Up Tumors Brighter Than Ever Before

Scientists at the Sanford Burnham Prebys Medical Discovery Institute (SBP) in San Diego, California have devised a way to optically image tumors with unprecedented clarity using quantum dots. These nano structures are tiny particles, only a few nanometers wide, that generate light of a specific wavelength when they’re themselves stimulated by (Read more...)

Nanocages Made of DNA Strands Release Small Molecules to Improve Challenging Studies Inside Body

Many of the activities happening within our bodies are incredibly difficult to study, as some happen in hard to reach places and their timespan is very short. The action of neurosteroids, chemicals that perform an important role in the lives of neurons, is one such topic. Neurosteroids take less than a second to act, and getting anywhere (Read more...)
