A coating that consists of a single-molecule-thick layer of a material called polyethylene glycol, with each molecule tipped with a "functional group" made with fluorine similar to PTFE, has reportedly been developed at Purdue University, A coating that consists of a single-molecule-thick layer of a ...
Electricity has been generated from the heat produced when organic molecules are trapped between metal nanoparticles, say researchers at the University of California, Berkeley. The nanoparticles arrangement acts as a mini thermoelectric converter. Th Electricity has been generated from the heat produced when organic molecules...
A three-dimensional microfabrication technique in which light-activated molecules selectively initiate chemical reactions within polymers and other materials has been reported by researchers at the Georgia Institute of Technology, Atlanta. The techno A three-dimensional microfabrication technique in which light-activated molecules selectively initiate chemical reactions within ...
In 1992, the Food and Drug Administration FDA published its policy statement on the development of new stereoisomeric drugs. The statement required all drugs with chiral centers to be studied with respect to their left and right enantiomers, or ste In 1992, the Food and Drug...
FADD Fas Associated protein with Death Domain is a key adaptor molecule transmitting the death signal mediated by death receptors. In addition, this multiple functional protein is implicated in survival/proliferation and cell cycle progression. FADD functions are regulated via cellular sublocalization, protein phosphorylation, and inhibitory molecules. The present review focuses...
The newest frontier in electronic miniaturization is molecular-scale electronics. But it is tough to manipulate single molecules so their electronic capabilities can be tested and applied. Researchers at Arizona State University have taken a s The newest frontier in...
This paper introduces a novel and highly reliable single-tube method for rapid cell lysis, followed by quantitative preparation and analysis of both RNA and/or DNA molecules in small samples. In contrast to previous approaches, this procedure allows all steps to be carried out by sequential dilution in a single tube,...
The adaptive immune system has the capacity to produce antibodies with a virtually infinite repertoire of specificities. Recombinant antibodies specific for human targets are established in the clinic as therapeutics and represent a major new class of drug. Therapeutic efficacy depends on the formation of complexes with target molecules and...
Saturated acyclic alkanes may show a high degree of strain if they have many branches close to each other. This paper reports calculations which indicate how strained a molecule may become before it falls apart rapidly at room temperature and so allow us to identify the simplest alkane which cannot...
PALO ALTO, Calif. -- Agilent Technologies Inc. (NYSE:A) today expanded its line of revolutionary, high-performance liquid chromatography HPLC chip/mass spectrometry MS modules, introducing five chips for the study of small and large molecules.
COMe (Co-Ordination of Metals) represents the ontology for bioinorganic and other small molecule centers in complex proteins. COMe consists of three types of entities: 'bioinorganic motif' BIM, 'molecule' MOL, and 'complex proteins' PRX, with each entity being assigned a unique identifier. A BIM consists of at least one centre (metal...
A single-step process for creating nonwoven fibrous mats from a small organic molecule is under development by scientists at Virginia Tech, Blacks-burg, Va. The nanoscale material may have potential as scaffolds for tissue growth and drug delivery A single-step process for creating nonwoven...
