Physicists of the University of Basel and the Swiss Nanoscience Institute were able to show for the first time that the nuclear spins of single molecules can be detected with the help of magnetic particles at room temperature. In Nature Nanotechnology, the researchers describe a novel experimental setup with which the tiny magnetic fields of the nuclear spins of single biomolecules - undetectable so far - could be registered for the first time. The proposed concept would improve medical diagnostics as well as analyses of biological and chemical samples in a decisive step forward.
In what marks a significant step forward for artificial intelligence, researchers at UC Santa Barbara have demonstrated the functionality of a simple artificial neural circuit. For the first time, a circuit of about 100 artificial synapses was proved to perform a simple version of a typical human task: image classification.
Imagine taking strands of DNA – the material in our cells that determines how we look and function – and using it to build tiny structures that can deliver drugs to targets within the body or take electronic miniaturization to a whole new level.
LGC is inviting nanotechnology manufacturers, standardisation organisations, regulators, research institutes and academia to a special workshop to mark the end of a three-year project to develop methods to characterise nanomaterials in complex matrices.
Hongjun Wang, PhD, associate professor of chemistry, chemical biology & biomedical engineering at Stevens Institute of Technology, has received a $50,000 Innovation Grant from New Jersey Health Foundation to advance research that may improve the quality and efficacy of dental implants, announced James M. Golubieski, president of NJHF.
Many experimental and clinical data have demonstrated that antibiotic-resistance pathogens, such as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), may play a vital role in priming chronic inflammation. There is thus a great need to develop novel antibacterial materials, and particularly those that are less likely to lead to bacterial resistance.
A microscopic tool, more than 1000 times thinner than the width of a single human hair, uses vibrations to simultaneously reveal the mass and the shape of a single molecule - a feat which has not been possible until now.
Functional analysis of a cell, which is the fundamental unit of life, is important for gaining new insights into medical and pharmaceutical fields. For efficiently studying cell functions, it is essential to reconstruct cellular microenvironments by parallel manipulation of single cells. Various cell manipulation techniques including fluidic, optical, and electrical techniques have been developed.
Using DESY's ultra bright X-ray source PETRA III, scientists have decoded the molecular and three-dimensional structure of two promising drug candidates from the new group of Spiegelmers for the first time. The results provide a deeper understanding of the mode of action of these substances that have already entered clinical trials. The researchers from the Universities of Hamburg and Aarhus (Denmark) together with colleagues from the biotech company NOXXON in Berlin present their work in the journal Nature Communications.
A new high-tech but simple ointment applied to the skin may one day help diabetic patients heal stubborn and painful ulcers on their feet, Northwestern University researchers report.
