Protein Coating Protects Nanoparticles from Immune Attack
Protein Coating Protects Nanoparticles from Immune Attack

clockMonday January 17, 2022

Researchers at the University of Pennsylvania School of Medicine have created a new coating for nanoparticles that can help to protect them from attacks by the immune system. The approach, which uses naturally occurring proteins that can inhibit the complement system, can significantly reduce immune destruction of nanoparticles, meaning that more may reach their target […]

Wearable Sensors Track Hand Use in Amputees
Wearable Sensors Track Hand Use in Amputees

clockThursday January 13, 2022

Researchers at the University of Missouri-Columbia have developed a system to track hand use in people with a hand prosthesis or patients who have undergone a hand transplant. The technology tracks movement in the hands and arms, and helps to monitor how people use their hands in everyday life. Such data could help to guide […]

Magnetic-Plasmonic Hybrid Nanoparticles Isolate Lysosomes from Cells

clockThursday January 13, 2022

Researchers at the Japan Advanced Institute of Science and Technology have developed a method to isolate intact lysosomes from cells. The technique is rapid and produces samples of high purity. Lysosomes are the garbage-disposal organelles within a cell, and they are involved in numerous diseases, from lysosomal storage diseases to autoimmune disorders, certain cancers, and […]

Optical Biopsy to Spot Tumors Among Healthy Tissue
Optical Biopsy to Spot Tumors Among Healthy Tissue

clockWednesday January 12, 2022

Researchers at Orel State University in Russia have developed a biopsy system that can distinguish between healthy and cancerous tissue in many clinical cases. The device is designed to address the difficulties that clinicians may experience when trying to obtain a biopsy of a liver tumor, where it can be difficult to know if the […]

Hairy Nanocrystals Capture Chemo Drugs

clockWednesday January 12, 2022

Researchers at Penn State working with collaborators have developed a nanomaterial that can ‘mop up’ chemotherapeutics in the bloodstream, helping to reduce off-target effects. The technology is intended for use in situations where a chemotherapeutic can be delivered precisely to the site of a tumor, and not in situations where it is delivered systemically. The […]

Water Vapor Plasma Bonding for Ultrathin and Flexible Electronics

clockTuesday January 11, 2022

Scientists at RIKEN research institute in Japan have developed a new method to bind gold electrodes to each other within flexible electronics. The technique, which does not require adhesives or high temperatures that can damage delicate electronic components, allows for extremely thin and flexible electronics and could lead to new types of medical wearables. The […]

Finger Clip for Blood Pressure Monitoring
Finger Clip for Blood Pressure Monitoring

clockWednesday January 05, 2022

At the University of Missouri a team of researchers developed a custom finger clip device that can continuously measure a variety of vitals, including blood pressure. The novel device represents a new way to measure vitals, and contains two commercial photoplethysmography (PPG) sensors that operate at two different points on the finger. This approach allows […]

Quantum Sensor to Detect SARS-CoV-2 More Accurately
Quantum Sensor to Detect SARS-CoV-2 More Accurately

clockTuesday January 04, 2022

Researchers at MIT have designed a quantum sensor to detect SARS-CoV-2. While the device is still theoretical, the researchers have used mathematical simulations to show its potential, and the data and design indicate that it may be faster, more accurate, and less expensive than the current gold-standard technique, PCR. The system is based on nanodiamonds […]

Pop-Up Sensors Measure Electronic Signals in Cardiac Cells
Pop-Up Sensors Measure Electronic Signals in Cardiac Cells

clockTuesday January 04, 2022

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 […]

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 […]

O2Ring Keeps an Eye on Your Blood Oxygen Level: A Medgadget Review
O2Ring Keeps an Eye on Your Blood Oxygen Level: A Medgadget Review

clockMonday December 27, 2021

We have all been living through a life-altering pandemic. As a result, words such as “oxygenation” and “pulse oximetry” have become mainstream and the general public has increased the use of pulse oximeters. This should come as no surprise since hypoxia (i.e., low blood oxygen level) is one of the hallmarks of COVID-19 pneumonia. Today, […]
