New material could enhance fast and accurate DNA sequencing
Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process.
'Trojan horse' gold nanoparticles treatment could beat brain tumors
A "Trojan horse" treatment for an aggressive form of brain cancer, which involves using tiny nanoparticles of gold to kill tumour cells, has been successfully tested by scientists.
Bioengineering team builds molecular motors to further the study of cell function
(Phys.org) —In every cell in your body, tiny protein motors are toiling away to keep you going. Moving muscles, dividing cells, twisting DNA – they are the workhorses of biology. But there is still uncertainty ...
Nanoscale, biodegradable drug-delivery method could provide a year or more of steady doses
About one in four older adults suffers from chronic pain. Many of those people take medication, usually as pills. But this is not an ideal way of treating pain: Patients must take medicine frequently, and ...
Nano-scale gold particles are good candidates for drug delivery
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
'Nanojuice' could improve how doctors examine the gut
Located deep in the human gut, the small intestine is not easy to examine. X-rays, MRIs and ultrasound images provide snapshots but each suffers limitations. Help is on the way.
Clot-building nanoparticles raise survival rate following blast trauma
A type of artificial platelet being developed to help natural blood platelets form clots faster offers promise for saving the lives of soldiers, as well as victims of car crashes and other severe trauma.
Scientists develop a 'nanosubmarine' that delivers complementary molecules inside cells
With the continuing need for very small devices in therapeutic applications, there is a growing demand for the development of nanoparticles that can transport and deliver drugs to target cells in the human ...
Nanoscale composites improve MRI: Researchers merge magnetic particles to detect, fight disease
(Phys.org) —Submicroscopic particles that contain even smaller particles of iron oxide could make magnetic resonance imaging (MRI) a far more powerful tool to detect and fight disease.
DNA-linked nanoparticles form switchable 'thin films' on a liquid surface
Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first—the formation of a single layer of nanoparticles on a liquid surface where ...
Targeting tumors using silver nanoparticles
Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique—and important—properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide ...
Design of self-assembling protein nanomachines starts to click
(Phys.org) —A route for constructing protein nanomachines engineered for specific applications may be closer to reality.
DNA nanotechnology places enzyme catalysis within an arm's length
Using molecules of DNA like an architectural scaffold, Arizona State University scientists, in collaboration with colleagues at the University of Michigan, have developed a 3-D artificial enzyme cascade that ...
Engineers build world's smallest, fastest nanomotor
Researchers at the Cockrell School of Engineering at The University of Texas at Austin have built the smallest, fastest and longest-running tiny synthetic motor to date. The team's nanomotor is an important ...
