New contact lenses allow wearers to see in the near-infrared

Devices use upconverting nanoparticles to make normally invisible radiation perceptible to humans even with their eyes closed

Ultrasound-activated structures clear biofilms from medical implants

Bioinspired technology could extend the safe lifespan of stents, catheters and other devices

Visual assistance system helps blind people navigate

A wearable navigation assistance system combines visual, audio and haptic senses to assist visually impaired people with daily life tasks

Light-activated pacemaker is smaller than a grain of rice

The world’s smallest temporary pacemaker is self-powered, optically controlled and dissolves when it’s no longer needed

Retinal stimulation reveals colour never before seen by the human eye

The Oz technique stimulates individual photoreceptor cells on the retina to directly control their activation

Oz principle for stimulating the human retina

Hydrogels rapidly switch from soft to hard to create smart medical bandage

Soft hydrogels can be moulded into a desired shape and then rapidly fixed into a high-strength version of that structure

Zwitterions make medical implants safer for patients

New coating material inhibits the build-up of proteins, reducing risk of blood clots

Photo showing a person's gloved hand using a pair of tweezers to hold a square of transparent material. Below the material is a beaker full of what looks like blood, but is actually water containing red food dye. The material looks to have been recently dipped in the dye, and the dye has clung to a spiral pattern "painted" onto the material with a zwitterionic coating. In the background are various objects indicating that this is happening in a laboratory.

Novel zinc alloys could make bone screws biodegradable

New coarser-grained alloys are strong enough to challenge stainless steel and titanium as materials for orthopaedic implants, say researchers

Photo of Feng Nei in the lab with his zinc alloy prototype. He's wearing glasses and a white lab coat and holding the prototype with metal tweezers, and is slightly out of focus so the emphasis is on the prototype, which is in focus. A rack of blue-lidded chemical bottles is on a shelf in the background.

Cell sorting device could detect circulating tumour cells

Researchers harness standing acoustic waves to separate microspheres that mimic circulating tumour cells in a blood sample

Nanosensor predicts risk of complications in early pregnancy

A flower-shaped nanosensor detects biomarkers in the blood associated with the risk of gestational diabetes and other pregnancy complications
