Miniaturized Optical Chip Can Identify Individual Biomolecules for Personalized Medicine
Researchers at Ecole Polytechnique Fédérale de Lausanne have developed an optical chip that can identify individual biomolecules in small sample volumes, using an ordinary camera and metasurfaces, an emerging technology in photonics. The...

Electronic Wound Monitoring Bandage Tracks Lactate, Oxygen Levels
Healing large and complex wounds requires vigilant monitoring and frequent dressing changes. This generally means pain, might require general anesthesia, and can even be emotionally disturbing to patients. A less invasive method of wound...

Real-Time Implantable Glutamate Sensor To Help with Neurotrauma, Other Conditions
The neurotransmitter glutamate seems to play an important part in a number of psychophysiologic processes. Migraines after spinal cord injuries, for example, are common typically due to a release of high concentrations of glutamate. Parkinson's...

Highly Sensitive Point-of-Care Sensor Measures Dopamine in Whole Blood
The concentration of dopamine in a patient's blood can be an important biomarker for a variety of diseases, including certain cancers, depression, and Parkinson's. Measuring dopamine in whole blood still requires a laboratory, making it slow and...

Multi-Parameter Sensors Detect Chemical and Physical Stimuli
Sensors are usually made to detect specific chemical or physical stimuli, making it difficult to create devices that can monitor a variety of different parameters at the same time. Now researchers at Technion-Israel Institute of Technology...

Handheld Melanoma Sensor Checks Suspect Lesions for Polarization Properties
Melanoma is usually a readily accessible cancer, being on the skin and in full view, but it can be hard to differentiate from benign moles. Researchers at the University of British Columbia have developed and tested a new device that uses a...

Hyperspectral Imaging Helps Spot Tumor Marking Tags Deep Within Body
Visualizing tumors deep within the body is difficult because light can only penetrate so far through tissues without losing most of the data it carries. Fluorescent markers that can highlight the existence of tumor cells have to be visible in...

Blood Test for Early Stage Cancer Diagnosis: Interview with Dr. Van Etten, CMO of Laboratory for Advanced Medicine
The Laboratory for Advanced Medicine (LAM), a biotechnology company headquartered in the US, offers non-invasive, early stage cancer detection tests that will use the IvyGene Platform. These IvyGene tests are based on detecting genomic DNA shed...

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...
