Thanks to billions of years of evolution, cells are remarkably adept at detecting pathogens or toxic chemicals in the environment. Taking advantage of this natural surveillance capability, researchers ...

2001 issue of the journal Science. 17 August 2001: Principles for Measurement of Chemical Exposure Based on Recognition-Driven Anchoring Transitions in Liquid Crystals, [abstract], Science.

Chemical engineers at the University of Wisconsin-Madison have developed a new way to create inexpensive chemical sensors for detecting explosives, industrial pollutants, or even the chemical markers ...

The worldwide pandemic COVID-19 has urged scientists around the world to concentrate their research on the virus. Some focused on understanding the fundamental aspects of the virus and its ...

Liquid crystals, with their uniform molecular structure and orientation, offer exciting possibilities for future technology. They are already the basis of displays, which use the crystals’ orientation ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

Schematic diagram providing an overview of this review. Liquid crystals can be categorized into nematic, smectic, columnar, and cholesteric liquid crystals. Recently, metasurfaces have been integrated ...

How many times have you stared at a home COVID-19 test, waiting for the faint line that confirms an infection? Those home antigen tests often fail to detect a recent infection or one with no symptoms.

Ions influence conductivity and mobility in molecular liquid crystals, affecting electrical behavior, stability, and performance in both established and emerging technologies. (Nanowerk Spotlight) The ...
