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 cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.
Researchers are developing a system that uses tiny magnetic beads to quickly detect rare types of cancer cells circulating in a patient's blood, an advance that could help medical doctors diagnose cancer earlier than now possible and monitor how well a patient is responding to therapy.
Work undertaken by the project 'Nano health-environment commented database' (NHECD) has culminated in a completely open-access database that incorporates a mechanism for updating the knowledge repository.
With high-tech optical tools and sophisticated mathematics, researchers have found a way to pinpoint the location of specific sequences along single strands of DNA, a technique that could someday help diagnose genetic diseases.
Atomically thin sheets of hexagonal boron nitride (h-BN) have the handy benefit of protecting what's underneath from oxidizing even at very high temperatures, Rice University researchers have discovered.
Nanotechnology is an emerging area that engages almost every technical discipline - from chemistry to computer science - in the study and application of extremely tiny materials. This short course allows any technically savvy person to go one layer beyond the surface of this broad topic to see the real substance behind the very small.
A new method developed by researchers at Princeton University and the University of Michigan called 'in silico nano-dissection' uses computers rather than scalpels to separate and identify genes from specific cell types, enabling the systematic study of genes involved in diseases.
