Scientists have introduced a novel contrast agent that marks tumor cells in vitro. The dye is a phosphorescent ruthenium complex incorporated into nanoparticles of a metal-organic coordination polymer, which allows an extraordinarily high level of dye loading.
A highly sensitive sensor that combines a variety of testing means (electrochemistry, spectroscopy and selective partitioning) into one device has been developed at the University of Cincinnati. It's already been tested in a variety of settings - including testing for components in nuclear waste.
A Syracuse University chemist has developed a way to use very low frequency light waves to study the weak forces (London dispersion forces) that hold molecules together in a crystal. This fundamental research could be applied to solve critical problems in drug research, manufacturing and quality control.
Structural studies of some of nature's most efficient light-harvesting systems are lighting the way for new generations of biologically inspired solar cell devices. Researchers from Washington University in St. Louis and the Department of Energy's Oak Ridge National Laboratory used small-angle neutron scattering to analyze the structure of chlorosomes in green photosynthetic bacteria.
Building on the success of the past two years, the N.C. Office of Science and Technology will host the 2011 N.C. Nanotechnology Commercialization Conference at the UNC Charlotte Barnhardt Student Center on March 29-30. The third annual conference brings together entrepreneurs, business leaders, researchers, and investors to accelerate the commercialization of nanotechnology and drive economic development.
A recently patented adhesive made by Kansas State University researchers could become a staple in every astronaut's toolbox. The patent, "pH dependent adhesive peptides", covers an adhesive made from peptides -- a compound containing two or more amino acids that link together -- that increases in strength as moisture is removed.
Scientists at the European Molecular Biology Laboratory (EMBL) and the German Cancer Research Centre (DKFZ) in Heidelberg in Germany have developed a method to uncover the combined effects of genes. The method should help scientists understand how different genes can amplify, cancel out or mask the effects of each other.
FutureMed, an executive program for physicians, healthcare executives, innovators and investors focused on exploring the impact of rapidly developing technologies on the future of health and biomedicine, is being held May 10-15 at Singularity University on the NASA-Ames Research Park in Silicon Valley.
A Pitt and Carnegie Mellon team developed a new model of how self-repairing materials function and show that materials with a certain number of easily breakable bonds can absorb more stress, a natural trick found in the resilient abalone shell.
Researchers at Brown may have come across the right formula to deter bacterial migrants. The group reports two ways in which it modified the surface of titanium leg implants to promote skin cell growth, thereby creating a natural skin layer and sealing the gap where the device has been implanted into the body. The researchers also created a molecular chain to sprinkle skin-growing proteins on the implant to hasten skin growth.
