Researchers at the University of Arkansas have developed a nanopore sensor to study the aggregation of tau and tubulin protein molecules. These proteins, and specifically their aggregation in the brain, are implicated in neurodegenerative diseases such as Parkinson’s and Alzheimer’s. This nanopore technology aims to allow researchers to study the effects of different environmental conditions, […]

Biobots Use Optogenetic Muscle Actuators for Movement
Researchers at the University of Illinois at Urbana-Champaign have developed centimeter-scale biobots that combine soft materials, mouse muscle tissue, and wireless electronic components. The tiny devices can be controlled remotely through optogenetics. The muscle within the devices forms an optogenetic actuator and creates movement when exposed to light. The researchers can control this movement remotely […]
Exciting Medtech at the Healthcareᐩ Expo Taiwan
Medgadget was recently invited to Taiwan to cover the 2022 Healthcareᐩ Expo in Taipei. As is the case for most trade shows, the exhibit hall comprised a large portion of the expo. Consisting of over 2000 exhibitors in two massive halls, the main hall showcased the best of Taiwan’s healthcare industry. Here are some notable […]
Medgadget Visits Healthcareᐩ Expo Taiwan
This past week, Medgadget was an official media partner with the Healthcareᐩ Expo Taiwan. This four-day annual event brings together healthcare companies from all over Taiwan and the rest of the world. It is also an opportunity for tech companies not typically associated with healthcare, such as ASUS, Intel, and BenQ, to showcase what they’re […]
Camera Measures Blood Pressure with Quick Look
At the University of South Australia, researchers designed a system that allows them to measure a patient’s blood pressure with a camera. The camera visualizes the patient’s forehead and focuses on two regions in particular to optically determine photoplethysmographic signals that AI algorithms then convert to blood pressure data. The researchers tested their system in […]
Diabetes Management Tech for Type II patients: Interview with Jeffrey Brewer, CEO of Bigfoot Biomedical
Bigfoot Biomedical, a medtech company based in California, has developed the Bigfoot Unity System, a diabetes management technology for patients on multiple daily injection therapy. The system uses continuous glucose monitoring data and doctor recommendations to provide insulin dose recommendations, helping patients to avoid uncertainty. The company argues that type 2 diabetes patients have been […]
Modified mRNA Demonstrates 10-Fold Protein Production
Scientists at Hong Kong University of Science and Technology came up with a technique to increase the efficiency and potentially the efficacy of mRNA therapeutics. mRNA molecules have what is called a poly-A tail, which is basically a string of adenine nucleotides at one end. These researchers discovered that by replacing some of these nucleotides […]
Toolbox to Study Ligand Binding for Enhanced Treatments
Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a DNA toolbox that allows researchers to explore binding interactions between ligands and their respective receptors based on receptor density and arrangement. The basis for many pharmacological interactions between drugs and cells, and indeed many physiological or pathological interactions involving biological signaling molecules, […]
Ferrobot Swarms for Rapid Viral Testing
At the University of California Los Angeles, scientists have developed a handheld lab kit that can conduct automated pooled testing for viral diseases, including COVID-19. The technology consists of a microfluidic platform that relies on swarms of magnetic discs, which the researchers have termed “ferrobots”, to shuttle samples through the device and mix them with […]
Making Tumors Tastier for the Immune System
Researchers at The University of Texas MD Anderson Cancer Center have developed a nanotechnology platform that can make cancer cells more vulnerable to immune attack in the body. The researchers call their system the bispecific tumor-transforming nanoconjugate (BiTN) platform. The idea is to make solid tumors more appealing for the immune system by attaching a […]
Device Measures Hemoglobin More Accurately in Dark Skin
Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, are inaccurate in […]
Improved Membrane Coating for Anti-Cancer Nanoparticles
Scientists at the University of Eastern Finland have developed a technique that lets them improve the coating of nanoparticles when using cell membranes. Cell membranes offer a lot of benefits as a coating for synthetic nanoparticles, including shielding from the immune system, prolonged circulation times and improved tumor accumulation. However, current approaches to coating nanoparticles […]
Magnetic Bacteria Target Tumors
Scientists at ETH Zurich in Switzerland have unveiled a technique that weaponizes bacterial cells against tumors. The approach involves using bacteria called Magnetospirillum that are naturally magnetic by virtue of the iron oxide particles they contain. The researchers use a rotating magnetic field applied at the tumor location from outside the body to help draw […]
Furry Soft Robot Helps Patients During Unpleasant Medical Procedures
A team of researchers at the University of Tsukuba in Japan has developed a fluffy soft robot that patients can interact with to reduce their stress and fear when undergoing painful or uncomfortable medical procedures. For some patients, particularly children, a fear of needles or uncomfortable and painful procedures can make such experiences especially challenging, […]
Impedance Cytometry for Rapid Antibiotic Susceptibility Testing
Scientists at Nara Institute of Science and Technology in Japan have come up with a method to rapidly determine the antibiotic susceptibility of a bacterial sample, such as a patient sample from a non-healing infected wound. The technique is based on impedance cytometry, which involves a high-throughput single cell analysis of the bacterial cells. The […]
3D Bioprinted Breast Tumors for Immunotherapy Testing
A team of scientists at Penn State has bioprinted breast tumor mimics with significant complexity, including a form of vascularization and the ability to precisely place cells in certain locations within the construct. The scientists used a technique called aspiration-assisted bioprinting to achieve this. With many anti-cancer therapies failing at the clinical trial stage and […]
Neck Sensor Helps Masked Clinicians Communicate
Researchers at Pohang University of Science & Technology in South Korea developed an auditory sensor that lets people wearing face masks, such as clinicians, to communicate more easily.

mRNA Therapy Prevents COVID Virus Entering Cells
Scientists at Oregon State University have developed a new treatment for COVID-19. The technology is based on mRNA, which has also been put to good use in COVID-19 vaccines. However, in this instance, the delivered mRNA encodes for human angiotensin-converting enzyme 2 (hACE2), which is the binding site for SARS-CoV-2 on airway cells. The lipid […]
Alzheimer’s Diagnostic Test Spots Amyloid β Exosomes in Blood
Researchers at Hokkaido University in Japan have developed a biomarker test for Alzheimer’s disease that detects amyloid β binding exosomes in a blood sample.
