Researchers from several CNRS-associated laboratories in France have succeeded in synthesizing porous nanoparticles that are capable of absorbing the energy of two photons in the near infrared spectrum, and then re-emitting radiation used for medical imaging by fluorescence.
Medical, environmental and chemical conundrums - including the mystery of how ice forms in the sky and goes on to create clouds - will be unravelled at a conference hosted by University College London to mark the opening of UCL's Materials Simulation Laboratory on Monday, March 31, 2008.
EarthSky Communications today announced the launch of a new series of 10 podcasts - focused on the emerging science of nanotechnology - as part of the nationwide Nanotechnology: Power of Small project.
A chemical engineer in the emerging field of nanomedicine, Chong Cheng says creating the tools to target tumors with powerful drugs - while bypassing healthy parts of the body - is the first step in achieving a future where cancer patients don?t suffer from the worst side affects of treatments such as chemotherapy.
Scientists have developed a new form of stretchable silicon integrated circuit that can wrap around complex shapes such as spheres, body parts and aircraft wings, and can operate during stretching, compressing, folding and other types of extreme mechanical deformations, without a reduction in electrical performance.
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer.
With the first Baby Boomer recently filing for Social Security, it is clear that more Americans will be living into their 80s and beyond. Responding to this trend, a new Penn State center will pursue interdisciplinary research that enhances independent living opportunities for older Americans in their homes and their communities and also fosters their physical, emotional and social well-being.
As a wide variety of nanoparticles continue to demonstrate their ability to improve the delivery of imaging agents and drugs to tumors, nanoparticle researchers have turned their attention to the challenge of systematically determining how a given nanoparticle's physical and chemical characteristics affect its ability to target tumors.
Researchers have created a technology based on stellar photometry software that provides more precise images of single molecules tagged with nanoprobes, particles specially designed to bind with a certain type of cell or molecule and illuminate when the target is found.
In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari of The University of Texas Health Science Center at Houston, presented a proof-of-concept study on a new multistage delivery system for imaging and therapeutic applications.
