3D Printed Microfluidic Bioreactor for Brain Organoid Culture

Researchers at MIT and the Indian Institute of Technology Madras have developed a 3D-printed microfluidic bioreactor that can be used to culture and study brain organoids. The tiny self-organizing nodules of brain tissue are very useful in studying neurological disease and the effects of drugs. However, the bioreactors used to grow brain organoids (Read more...)

Sticker on Skin Diagnoses Cystic Fibrosis in Real-time

Researchers at Northwestern University have developed a sticker that can measure chloride levels in sweat in real-time through a simple color change. The sticker is applied to the skin and wicks sweat inside itself through a set of microfluidic channels, where an onboard bioassay measures chloride levels, a marker of cystic fibrosis. The technology (Read more...)

Quick and Easy CRISPR COVID Test Spots Mutations

Researchers at Nanyang Technological University, Singapore (NTU Singapore) have developed an easy to perform CRISPR-based COVID-19 test that takes only 30 minutes for the results to come in. The test, which involves dipping a paper strip into a mixture containing a nasal sample, can identify various new variants of the virus, and could be useful [& (Read more...)

Hummingbird Device for Ear Tube Placement: Interview with Steve Anderson, CEO of Preceptis Medical

In the United States approximately 1 million children undergo ear tube placement every year. The tubes are typically needed when there’s excess fluid in the middle ear and to address chronic ear infections. The tubes help to prevent this fluid build-up but require placement under general anesthesia. General anesthesia can be distressing for c (Read more...)

Mussel Protein Bioglue to Seal Fistulas Inside Body

Researchers at Pohang University of Science & Technology in Korea have developed a bioglue, containing a mussel adhesive protein and hyaluronic acid, that can seal fistulas within the body. It works even on fistulas present in particularly challenging areas, such as the wall of the bladder. The researchers delivered the glue using a thin syring (Read more...)

Micro-Aneurysm-On-A-Chip to Model Vascular Disease

An international research collaboration, including teams from Nanyang Technological University, Singapore (NTU Singapore), Brown University, and MIT, has developed an AI platform that can assess blood flow characteristics through microvasculature. The system relies on a microfluidic chip that mimics vascular disease, in this case a micro-aneurysm i (Read more...)

Near-Infrared Hyperspectral Imaging Detects Liver Fat Content

Researchers at the Tokyo University of Science have applied a new imaging technique in a way that may allow clinicians to assess liver fat content without having to take biopsies. Called near-infrared hyperspectral imaging, the method can highlight fat distribution in liver tissue, potentially helping clinicians to diagnose and assess conditions su (Read more...)

Lab-Generated Heart Valves Grow Inside Body

Researchers at the University of Minnesota have developed a tissue-engineered heart valve replacement that can grow within a patient. The breakthrough could allow children with congenital heart defects to avoid repeated surgeries to replace heart valves that they have outgrown. To create the valves, the researchers cultured donor cells in a fibrin (Read more...)

Medical Robotics and The Future of Surgery: Interview with Tracy Accardi, VP of R&D at Medtronic

Medtronic has been a key player in the minimally invasive surgery space for the last few decades, and has made great strides more recently in robotic surgery with last year’s acquisition of Digital Surgery. As a quick reference point: despite the many benefits of robotic-assisted surgery (RAS), only 3% of surgeries around the world are [&hell (Read more...)

Silver-Hydrogel Composite for Bioelectronic Applications

Researchers at Carnegie Mellon University have developed a silver-hydrogel composite that can conduct electricity, which looks promising for use in a variety of bioelectronics applications. These include skin mounted electrodes for neuromuscular stimulation that may be helpful in treating muscular disorders or other motor issues. Soft materials are (Read more...)

Smart Speaker Monitors Heart Rhythms

Researchers at the University of Washington have developed an AI-powered sound system that can detect irregular heartbeats. The system sends inaudible sounds into its close environment and then analyzes the reflected waves to identify individual heartbeats from someone sitting close to it. The technology may be useful in detecting heart rhythm diso (Read more...)
