By attaching a hydrogen peroxide reporter protein to cellular microtubule structures, researchers have developed the first sensor able to show the location of the key cellular signaling chemical inside living cells with high resolution over time.
Despite being thousands of times thinner than a sheet of paper and hundreds of times thinner than household cling wrap or aluminum foil, corrugated plates of aluminum oxide spring back to their original shape after being bent and twisted.
Using a novel microscope that combines standard through-the-lens viewing with a technique called scatterfield imaging, researchers accurately measured patterned features on a silicon wafer that were 30 times smaller than the wavelength of light (450 nanometers) used to examine them.
Researchers who pioneered the development of laser-induced graphene have configured their discovery into flexible, solid-state microsupercapacitors that rival the best available for energy storage and delivery.
The development of a reusable microfluidic device for sorting and manipulating cells and other micro/nano meter scale objects will make biomedical diagnosis of diseases cheaper and more convenient in regions where medical facilities are sparse or cost is prohibitive.
Viscous nanopores, tiny holes punctured in fluid membranes, collapse according to a universal law, a study shows. The finding could improve the design of nanopores for fast, inexpensive DNA analysis and sheds light on the biology of pores in cell membranes.
If quantum computers existed, they would revolutionize computing as we know it. Based on fundamental properties of matter, the potential power of these theoretical workhorses would solve problems in a new way, cracking extremely complex spy codes and precisely modeling chemical systems in a snap. Now, researchers have created cleverly designed molecules to get one step closer to this goal.
