Ultra-sensitive Lead Detector Could Significantly Improve Water Quality Monitoring

February 5, 2024

Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.

‘Gold Standard’ Research Presents Promise for Plasmonic Devices

May 31, 2018

…And, while plasmons have found commercial applications in chemical sensors (e.g., common drug-store pregnancy tests), they have not been applied more widely or ambitiously because of high dissipation, which has frustrated scientists—until now.

Physicists Fine Tune Control of Agile Exotic Materials

June 23, 2015

Physicists have found a way to control the length and strength of waves of atomic motion that have promising potential uses such as fine-scale imaging and the transmission of information within tight spaces.

Human Brain Organoids Implanted into Mouse Cortex Respond to Visual Stimuli for First Time

December 28, 2022

A team of engineers and neuroscientists has demonstrated for the first time that human brain organoids implanted in mice have established functional connectivity to the animals’ cortex and responded to external sensory stimuli.

Nanoshaping Method Points to Future Manufacturing Technology

January 12, 2015

A new method that creates large-area patterns of three-dimensional nanoshapes from metal sheets represents a potential manufacturing system to inexpensively mass produce innovations such as “plasmonic metamaterials” for advanced technologies.
