A new material changes its conductivity depending on the concentration of carbon dioxide in the environment. The researchers who developed it have utilized the material to produce a miniature, simply constructed sensor.

Two young researchers have developed an ultracompact highly sensitive nanomechanical sensor for analyzing the chemical composition of substances and detecting biological objects, such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others. The sensor will enable doctors to identify tumor markers, whose presence in the body signals the emergence and growth of cancerous tumors.

Researchers have created wearable sensor patches that detect harmful UV radiation and dangerous, toxic gases such as hydrogen and nitrogen dioxide.

Imagine being able to test your food in your very own kitchen to quickly determine if it carried any deadly microbes. New research may make that possible.

New research has shown how a smart sensor chip, able to pick up on subtle differences in glycoprotein molecules, can improve the accuracy and efficiency of prostate cancer diagnosis.

A new type of sensor, that is much faster than competing technologies used to detect and identify hidden objects, has been developed by scientists.
