These nanorobots clear bacteria and toxins from blood

Researchers at the University of California at San Diego have created tiny ultrasound-powered nanorobots that are designed to swim through blood and remove bacteria and toxins. The UCSD researchers built the nanorobots using gold nanowires coated with a hybrid of platelet and red blood cell membranes. The hybrid coating meant the nanorobots can perform two

How you can control lab-grown heart cells with a remote control light

University of California San Diego researchers have created a technique that speeds up and slows down human heart cells that are being grown in a dish on command by shining light on them and varying the intensity. The heart cells are being grown in graphene which turns light into electricity, a more realistic environment that

This tattoo-like sensor measures blood glucose levels non-invasively

Diabetes tracking can be a scary and tedious task, but University of California at San Diego researchers have developed a needless glucose monitor tattoo sensor that measures insulin levels through sweat on the skin. There are approximately 30.3 million people living with diabetes in the U.S., according to the American Diabetes Association. Monitoring blood sugar

This wearable system continuously monitors stomach activity

California researchers have created an electrocardiogram-like system for the gastrointestinal tract that monitors electrical activity in the stomach over a 24-hour period. The system is a wearable, non-invasive system that provides GI activity monitoring outside of clinical settings while increasing the chance of identifying abnormal activity. It is a 3D printed portable box that is

This smartphone case monitors blood glucose on the go

University of California San Diego engineers have created a smartphone case that, when paired with an app, can make it easier for people with diabetes to track and record blood glucose levels on the go. “Integrating blood glucose sensing into a smartphone would eliminate the need for patients to carry a separate device,” Patrick Mercier,

This remote-controlled immunotherapy system targets and kills cancer cells

University of California researchers have developed a remote-controlled therapy system that identifies and kills cancer cells using ultrasound. The ultrasound-based system is able to non-invasively and remotely control the genetic process in immune T cells to identify and kill cancer cells. According to the researchers, the ability to non-invasively and remotely manipulate cells at a

These nanosponges remove sepsis-causing bacteria from the bloodstream

California researchers have created a nanosponge that is designed to absorb and remove molecules that are known to cause sepsis. Researchers from the University of California at San Diego created macrophage nanosponges that are wrapped in the cell membranes of macrophages and can safely absorb and remove sepsis-causing molecules from the bloodstream. So far, the

This sweat-powered biofuel cell could create better wearable devices

Engineers at the University of California at San Diego have created a stretchable sweat-powered biofuel cell, and it could enable better wearables. The biofuel cells use energy from sweat to generate 10 times more power per surface area than other biofuel cells that are used in wearables. The researchers claim it could be used to

How squid ink could make going to the dentist painless

Squid ink could be used as a new imaging method at the dentist to check for gum disease, according to new research from the University of California at San Diego. Combining squid ink with light and ultrasound, engineers at UCSD have created a new dental imaging method that can painlessly and non-invasively examine a patient’s

Could this temperature sensor reduce power consumption in medical devices?

A new temperature sensor that runs at 113 pW could make wearables and even implantable medical devices less power dependent, according to research from the University of California at San Diego. The temperature sensor, developed by electrical engineers at UCSD, uses about 628 times lower power than state-of-the-art power sources and is 10 billion times

This retinal prosthetic could restore sight in blind people

University of California San Diego engineers have collaborated with the startup company Nanovision Biosciences to create nanotechnology and wireless electronics that can be used as a retinal prosthesis. The prosthesis is designed to help restore the ability of retinal neurons to respond to light. This is not the first example of prosthetic retinas. Current retinal
