Novel Microneedle Drug Delivery Patch for Burning Fat

Obesity results from excess white fat storage, making it difficult to treat because the effectiveness of diet, exercise, and systemic anti-obesity agents is limited, and in the latter case may cause serious side effects. As a result, researchers are investigating innovative strategies for localized delivery of fat burning compounds via transdermal (Read more...)

Nanoparticle-Based Imaging of Metastasis Throughout Body

Common radiological tumor detection technique these days is done using contrast-enhanced magnetic resonance imaging (MRI), which can only detect tumors of a certain size or larger. This is a major limitation, as it leaves patients with smaller tumors that grow and spread undetected, preventing early treatment of many cancers. Researchers at Rutgers (Read more...)

Magnetically Guided Bacteria Move Confidently Within Strong Currents, May Soon Deliver Drugs Inside Body

Researchers at Queen’s University in Canada have managed to get a special type of bacteria to swim against a strong current, opening up the possibility of using the organisms as drug delivery vehicles. The team is using magnetotactic bacteria which have magnetic crystals within them and naturally orient themselves with the Eart (Read more...)

Guided Microrobots Made of Algae and Magnetic Particles

Researchers have developed microrobots using algae and magnetic particles that can be guided magnetically to sites in the body and tracked, by spotting the algae’s natural luminescence or using an MRI scanner. The investigators hope that swarms of these tiny robots could help with diagnostics and treatment in areas of the body that are curren (Read more...)

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...)
