RNA carried by new nanoparticles can silence genes in many organs, could be deployed to treat cancer
RNA interference (RNAi), a technique that can turn off specific genes inside living cells, holds great potential for treating many diseases caused by malfunctioning genes. However, it has been difficult for ...
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 ...
Nanostructure of 5,000-year-old mummy skin reveals insight into mummification process
Better RNA interference, inspired by nature: New nanoparticles offer best-ever gene silencing
Inspired by tiny particles that carry cholesterol through the body, MIT chemical engineers have designed nanoparticles that can deliver snippets of genetic material that turn off disease-causing genes.
'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.
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 ...
Chemists design nanoparticles that can deliver three cancer drugs at a time
Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. In recent years, scientists have developed nanoparticles that deliver one or ...
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.
Cells prefer nanodiscs over nanorods
For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into ...
New method sneaks drugs into cancer cells before triggering release
(Phys.org) —Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened ...
Biomolecular tweezers facilitate study of mechanical force effects on cells and proteins
A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices – too small to see without a microscope – use ...
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.
Mice study enables view of nanoparticle accumulation
Surface characteristics influence cellular growth on semiconductor material
(Phys.org) —Changing the texture and surface characteristics of a semiconductor material at the nanoscale can influence the way that neural cells grow on the material.
