...nished with this source would make nanometer-sized biomolecules perceivable in their natural surrounding (in vivo). It may take many years before this dream comes true, but the experiment reported by an Austrian-German collaboration led by Ferenc Krausz indicates a promising way of realizing the dream some day. R...

Motor transport in bio-nano systems

...may witness the development of sorting devices for biomolecules and biocolloids, drug delivery systems that utilize the motor transport within human cells, and motile components for nanoscale manufacturing. Long term, we should also be able to construct 'smart' biomimetic systems which are able to respond to and ...

By creating molecular 'bridge,' scientists change function of a protein

...hod may provide "a general approach to engineering biomolecules and biosystems such as receptors, enzymes, antibodies, ribosymes, DNAzymes and viruses with novel functions." Zhao is a member of the Institute for Genomic Biology and the Center for Biophysics and Computational Biology at Illinois. He also is an aff...

...up works with calcium channel modulators and other biomolecules derived from plants and scorpion venom. But when Pessah and Molinski got to talking at a party some years ago, they quickly realized that they could apply the same methods to screen 124 sponges that Molinski's group had recently collected off the coa...

ASU researcher fashions DNA to further advances in nanotechnology

...isioned as scaffolds for directing the assembly of biomolecules such as proteins into a functional network," said Yan. "However, the methods to control such assemblies are still scarce. A robust and modular approach is needed. " In his results, Yan and fellow institute researchers Yan Liu, Chenxiang Lin, and Han...

Amazing nanotech in Boston: Weighing DNA, digital heat flow, electromechanical butterfly images

...ter sensitivity in locating and identifying single biomolecules by measuring their masses. A typical NEMS sensor consists of an oscillating slab so small in size and mass that even if a single DNA molecule were to alight on it, the slab's resonant frequency (the vibration rate it maintains once set in motion) wou...

The slide is licensed to Diversified Biotech of Boston, which is working with Erie Scientific Company of Po...

The dynamic personalities of proteins reveal key traits

...with or without the ball nature has evolved these biomolecules so that they are constantly moving in highly-defined directions conducive to their function with or without the substrate," explained Kern, who played for the East German National basketball team before the Berlin Wall fell in 1989 and later professi...

Clay material may have acted as 'primordial womb' for first organic molecules

...clay minerals can help produce the ingredients for biomolecules (chemical components used by living organisms)," Williams said. Because the reactions simulated in these experiments can be found anywhere volcanic activity exists, Williams added, it is likely that similar organic compounds could be produced on othe...

Biotechnology's newest chemical tool

...this technique is likely to be applicable to those biomolecules as well, further expanding its utility. Klimasauskas said that one potential application might be to label various sites in the ribosome -- the RNA-based site of protein production -- with bright fluorophores using appropriate RNA methyltransferases,...

Alcohol-induced bone disease

..."This is first formed as a soft tissue, containing biomolecules that are unique to bone, that later hardens or becomes calcified. Alcohol consumption changes the composition of this matrix by suppressing the formation of osteoblasts and/or decreasing their ability to respond to signals that normally trigger bone...

Yang recently received a $1.28 million, five-year grant from the National Institutes of Health to study cancer drug delivery. Yang said researchers face multiple ...

Nanoparticles create biocompatible capsules

...me-catalyzed reactions are performed. By attaching biomolecules to the capsule's surface, novel colloidal-size sensors could be produced. An additional use for stabilized lipid capsules is the study of drug behavior. "A drug contained in this nano environment is like a fish swimming inside a bowl," Granick said. ...
