Tiny nanoprobes have shown to be effective in delivering cancer drugs more directly to tumor cells - mitigating the damage to nearby healthy cells - and Purdue University research has shown that the nanoprobes are getting the drugs to right cellular compartments.
Scientists have identified a novel antifreeze molecule in a freeze-tolerant Alaska beetle able to survive temperatures below minus 100 degrees Fahrenheit. Unlike all previously described biological antifreezes that contain protein, this new molecule, called xylomannan, has little or no protein.
Researchers at Rice University and Baylor College of Medicine (BCM) have created a single nanoparticle that can be tracked in real time with MRI as it homes in on cancer cells, tags them with a fluorescent dye and kills them with heat.
Binden Antikoerper des Immunsystems an Proteine, koennen sie deren Form - und damit auch die Funktion dieser Molekuele - veraendern. Einem LMU-Team gelang hier nun ein Durchbruch: Die Forscher konnten zeigen, dass unkonventionell kleine Antikoerper, die sogenannten Nanobodies, die Eigenschaften des Gruen Fluoreszierenden Proteins, kurz GFP, mit unerwarteter Praezision modifizieren.
A spectroscope with unrivalled performance, able to identify tiny amounts of trace gases in real time, has been developed by researchers from CNRS's Molecular Photophysics Institute and the Max Planck Institute of Quantum Optics (Germany), within the framework of the European Laboratory for Frequency Comb Spectroscopy.
Johns Hopkins biomedical engineers, working with colleagues in Korea, have produced a laboratory chip with nanoscopic grooves and ridges capable of growing cardiac tissue that more closely resembles natural heart muscle. Surprisingly, heart cells cultured in this way used a 'nanosense' to collect instructions for growth and function solely from the physical patterns on the nanotextured chip and did not require any special chemical cues to steer the tissue development in distinct ways.
In future, it will be possible to quickly analyse DNA from pathogenic bacteria via an online so-lution which at same time collects and shows information on species, strains and antimicrobial resistance on web-based world maps. This can contribute to reduce and prevent the global spread of contagious diseases. These are among the perspectives behind the Centre for Molecular Epidemiology which can now be established at Technical University of Denmark.
Senior policymakers and experts in the defense and cleantech industries got a boost today with the announced formation of the NanoAssociation for Natural Resources and Energy Security (NANRES). NANRES is a trade organization designed to advance the research, development, and commercialization of innovative energy and environmental-specific nanotechnologies.
Scientists have resolved a question about how a popular class of drugs used to treat schizophrenia works using biosensors that reveal previously hidden components of chemical communication in the brain.
A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings could dramatically simplify the way physicians test for biomarkers of cancer and other diseases.
