Pop-Up Sensors Measure Electronic Signals in Cardiac Cells

Researchers at University of California San Diego have developed a tiny ‘pop-up’ sensor that can measure the electronic signals propagating inside cardiac cells. The technology consists of tiny spike-like protrusions that can penetrate cell membranes without causing damage, and which can detect electrical signals within individual cells and between cells in 3D tissue samples. The […]

Thought-to-Text Brain-Computer Interface: Interview with Florian Solzbacher, Chairman of Blackrock Neurotech

Blackrock Neurotech, a medical technology company based in Salt Lake City, created a suite of brain-computer interface systems with the goal of empowering patients to have increased independence and quality of life. This latest technology aims to restore written communication in patients who have difficulties in this regard, such as those affected by paralysis. The […]

Crossing the Blood-Brain Barrier Using Lasers and Gold Nanoparticles

Delivering drugs to the brain remains a challenge due to the blood-brain barrier, a specialized endothelial layer that is highly selective in what it permits into the neural tissue beyond. At the University of Texas at Dallas, researchers have developed a technique that allows therapeutics to cross the blood-brain barrier, potentially allowing for new treatments […]

Wristband to Detect Strokes: Interview with Sandra Saldana, CEO of Alva Health

Alva Health, a medtech startup based in Connecticut, is developing a wristband that can detect the signs of stroke and promptly alert the wearer and/or healthcare staff. The technology is intended for those at high risk of stroke, such as stroke survivors and those diagnosed with transient ischemic attack. Strokes cause a huge level of […]

Laser-Assisted Bioprinting of Neurons

A team at Concordia University in Montreal have developed a technique called Laser-Induced Side Transfer (LIST) that allows for bioprinting of neurons. Low energy laser pulses are directed at a capillary containing a cell-laden bioink, resulting in microbubbles that eject a microjet of the ink onto the substrate below. The technique appears to be fairly […]

EEG Test for Early Alzheimer’s Diagnosis

Researchers at the University of Bath in the UK have developed an EEG test for Alzheimer’s disease. The technique involves measuring brain waves using an EEG cap while a person watches a screen with a series of flashing images. Taking just two minutes, the test quantifies a person’s ability to differentiate between images based on […]
