Mimicking this process using human-made polymer systems, however, has remained limited. Previously developed processes for self-assembling drug delivery systems are time consuming, labor intensive and difficult to scale. The processes also tend to be woefully inefficient, culminat.. Bone marrow targeted nano-particle RNA interference is a strategy that could potentially be used to treat a variety of diseases by delivering short strands of RNA that block specific genes from being turned on in a cell. So far, the biggest obstacle to this kind of therapy has been the difficulty in delivering it to the right part of the body. When injected into the bloodstream, nanoparticles carrying RNA tend to accumulate in th.. nano device mimicking neuron - nature *** To build the fundamental building block of the brain or a neuron, the researchers assembled a synthetic nanoscale device consisting of layers of different inorganic materials, each with a unique function. However, they said the real magic happens in the thin layer made of the compound niobium dioxide When a small voltage is applied to this region, its temperature begins to increase. But when the.. droplet manipulation using photo The fluidic platform facilitated the development of a unique wavy dielectrophoretic force field from a single beam of light to remarkably perform the desired loss-free manipulation of droplets and function as a "magic" wetting-proof surface. The liquid platform could navigate, fuse, pinch and cleave fluids on demand to establish cargo carriers with droplet wheels and has potential to upgrade the.. how gut bacteria sticks to gut Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Cellulose is a major building block of plant cell walls, consisting of molecules linked together into solid fibers. For humans, cellulose is indigestible, and the majority of gut bacteria lack th.. antigen detection on LFA by using glycan The new diagnostic tool uses glycans (sugars) to detect the virus, using a tool very similar to a home pregnancy test. "The rapid detection of the virus, for both healthcare and to enable society to return to normal is crucial. Our technology, developed through joint Ph.D. student work with our industry partners, makes use of glyco-nanomaterials to detect a specific portion of the coronavirus. T.. Increasing membrane surface tension: Malaria resistance The team found that red blood cells in people with the rare Dantu blood variant have a higher surface tension that prevents them from being invaded by the world's deadliest malaria parasite, Plasmodium falciparum. Because the surface tension of human red blood cells increases as they age, it may be possible to design drugs that imitate this natural process to prevent malaria infection or reduce .. 이전 1 2 3 4 5 6 ··· 19 다음
