The sensor principle is based on a red and a green fluorescent dye. If a substance to be detected is present in a water sample, then the sensor shines green; a red color, however, indicates that the substance is not present.
At this week's International Image Sensor Workshop (IISW 2013, Snowbird, US, June 12-16 2013), imec and Holst Centre present a large-area fully-organic photodetector array fabricated on a flexible substrate. The imager is sensitive in the wavelength range suitable for x-ray imaging applications.
New research shows that exposing polymer molecular sieve membranes to ultraviolet (UV) irradiation in the presence of oxygen produces highly permeable and selective membranes for more efficient molecular-level separation, an essential process in everything from water purification to controlling gas emissions.
Scientists have been able to show ways in which we can markedly improve drug targeting of solid tumors, using tiny 'biosensors' along with new advanced imaging techniques. In real time and in three dimensions, these technologies can show us how cancers spread and how active cancer cells respond to a particular drug.
Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures - including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals.
New, more efficient drug formulations designed to treat illnesses through skin applications - thus avoiding serious side effects associated with oral drug-taking - have been developed by a student at the Hebrew University of Jerusalem. The method is based on utilizing skin-permeable proteins that are inserted into nano-structured gels.
Mobile phones that bend, self-powered nanodevices, new and improved solar cell technology and windows that generate electricity are but a few of the potential products from the union of semiconductors and graphene.
Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate, findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft.
Now in its fourth year, Nanoweek will celebrate the importance of nanoscience to the Irish economy; the excellence of nanoscience research within our universities, and look to grow public awareness of a technology which is fundamental to medicine, communications, pharmaceuticals, energy and transport among other industries.
A new study found that the shape of nanoparticles can enhance drug targeting. According to this study, rod-shaped nanoparticles - or nanorods - as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells that line the inside of blood vessels.
