Tiny Microrobot Created Using Silicon Wafers Could Aid in Drug Delivery
Researchers at the University of Pennsylvania have developed wireless bug-shaped microrobots using nanofabrication techniques. They are able to produce a million of the devices from a 4-inch silicon wafer. The microrobots can “walk,” survive...

Researchers Give Animals Infrared Vision
Even those of us with perfect vision are actually blind in some ways. Many birds can see ultraviolet light and snakes can detect infrared, something we don't have the right retinal cells for. But now researchers at University of Massachusetts...

Microfluidic Device Pulls Exosomes from Blood to Test for Cancer
Exosomes are tiny vesicles that seemingly all the cells in our bodies produce. Initially, exosomes were thought to be a way for cells to expunge built-up trash, but over the past decade or so scientists have discovered that they seem to play an...

Microfluidic Device Separates Circulating Tumor Cells by Size to Help Spot Cancer
Tumors tend to shed cells that travel down the bloodstream, spreading the disease wherever they end up landing. Though these circulating tumor cells (CTCs) are the reason that cancers metastasize to distant places in the body, they're also a...

Self-Assembled Hybrid Drug Delivery Vesicles for Safe Passage Through Bloodstream
Scientists at the RIKEN research institution in Japan have developed new soft nanovesicles to carry and release drugs within the body. The hybrid shells, made of lipids and peptides, open up and release their cargo when exposed to heat. The...

Nanoparticles Highlight Organ Transplant Rejection Through Fluorescent Urine
Researchers at Georgia Tech have developed a sophisticated nanoparticle that can alert clinicians to the early stages of transplanted organ immune rejection through a simple urine test. The nanoparticles can accumulate in transplanted organs and...

Microrobots Take Minutes to Detect C. diff in Stool Samples
Detecting bacterial infestations within the GI system, particularly using low cost methods, takes so much time that treatment is often administered too late. Clostridium difficile (C. diff) is a particular nasty nuisance that kills many frail...

Graphene Biosensors to Detect Lung Cancer
Exhaled breath is rich in biomarkers that can point to the presence of disease. In particular, ethanol, acetone, and isopropanol can point to the presence of lung cancer, so having a way of measuring these chemicals in breath might provide a way...

Microrobots Swim Through Vessels, Deform to Snake Through Tortuous Passageways
Researchers at Ecole polytechnique fédérale de Lausanne and ETH Zurich in Switzerland have developed tiny robots that could pave the way for advanced drug delivery. Inspired by bacteria, the microrobots can swim through fluids and modify their...
