New sensors developed by Professor Otto Gregory, of the College of Engineering at the University of Rhode Island, and chemical engineering doctoral student Peter Ricci, are so powerful that they can detect threats at the molecular level.
A new method to analyse the blood thinning drug Heparin has been developed that can pinpoint contaminants more accurately and quickly, providing greater quality control and safety.
Low-dimensional materials, such as 1D monoatomic chains, exhibit exotic properties that could find interesting applications. However, single-atom bonds and their mechanical characteristics are difficult to study. In a recent study, scientists from JAIST, Japan, showcase a novel method to simultaneously image monoatomic platinum chains with a transmission electron microscope while measuring their bond strength and conductance during mechanical stretching. This technique will help answer many questions in the fields of nanomechanics and surface science.
Osaka University researchers employed machine learning to remove the noise from experimental data without the need for "clean" examples. As a result, the team was better able to monitor the motion of spheres through tiny nanopores. This work may lead to advances in the fast detection of even very small concentrations of pathogens in patient samples.
The demonstration that a tiny cloud of atoms can be turned from a heat engine into a cooler by cranking up the interactions between the particles provides both deep fundamental insight and a possible template for more efficient thermoelectric devices.
World-first nanotechnology developed by the University of South Australia could change the lives of thousands of people living with cystic fibrosis (CF) as groundbreaking research shows it can improve the effectiveness of the CF antibiotic Tobramycin, increasing its efficacy by up to 100,000-fold.
A Z-RNA nanoswitch, less than 5 nanometer in length, flips from the right-handed A-RNA helix (?on") to the left-handed Z-RNA helix (?off") to selectively turn "off" immune responses against self RNAs, while allowing those against viruses to continue. Surprisingly, the Z-RNA nanoswitch sequence is encoded by "junk DNA". The Z-RNA nanoswitch is used by some cancers to silence anti-tumor immune responses. In other cases, a malfunction of the Z-RNA nanoswitch causes inflammatory disease.
Tie Jun Cui, professor at Southeast University's Institute of Electromagnetic Space, remarks, "Glide symmetry offers powerful and flexible control of SSPPs and may bring about new solutions in future integrated circuits." Cui envisions that when serious line-to-line interference damages the performance of circuits, an alternating arrangement of glide and nonglide symmetric TLs can restore and guarantee signal accuracy.
Chemically synthesized short DNA sequences are extremely important ingredients with countless uses in research laboratories, hospitals and in industry, like in detecting COVID-19. Phosporamidites are necessary building blocks in the production of DNA sequences, but break quickly. Researchers from Interdisciplinary Nanoscience Center (iNANO) and Department of Chemistry at Aarhus University have developed a new patented way to efficiently manufacture the unstable building blocks immediately before they are to be used and thus streamline DNA production
Researchers from the National University of Singapore have created a new class of intelligent materials. It has the structure of a two-dimensional (2D) material, but behaves like an electrolyte - and could be a new way to deliver drugs within the body.
