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...

Electronic Nanomesh Gently Hugs Beating Heart Cells
Unlike with most other cells, studying the heart's beating cardiomyocytes is prone to difficulty because attaching rigid sensors to moving cells hinders the movement of those cells. A collaboration of Japanese scientists at University of...

Contrast Agent for Optical Coherence Tomography Improves Imaging of Tissues, Vessels
Optical coherence tomography (OCT) is an imaging technique that allows ophthalmologists to view the eye's blood vessels, to study the structure of tissues in various clinical and scientific applications. Though this technology is already widely...

New Sensor Detects HER-2 Breast Cancer Biomarker in 15 Minutes
A few years ago researchers identified the Human Epidermal Growth Factor Receptor 2 (HER-2) protein as a biomarker for the presence of certain types of breast cancer. Tests for it, though, are expensive and take much time to produce results....
