If you had brain tumor, would you rather receive your medicine through an injection in the arm or have a hole drilled in your skull? One of the most important applications of nanotechnology could be drug delivery by nanoparticles (or nanoshells) in particular into the brain. An international group of researchers developed a novel targeted nanoparticulate drug delivery system for the brain
Nanoscopic medicine refers to the direct visualization, analysis (diagnosis) and modification (therapy) of nanoscopic protein machines in life cells and tissues with the aim to improve human health.
A new review highlights the recent advances and progress in bionanotechnology by providing examples of current state-of-the-art research and then takes a look at the future perspective for the field.
Liposomes, man-made cells used as drug delivery vehicles, would be more useful if only they could be stabilized against fusion with one another. Researchers at the University of Illinois told Nanowerk that they succeeded in doing exactly that - they stabilized phospholipid liposomes with charged nanoparticles, thereby opening up interesting functional perspectives.
The responses of cells exposed to nanoparticles have been studied with regard to toxicity, but very little attention has been paid to the possibility that some types of particles can protect cells from various forms of lethal stress.
Spanish researchers developed a simple and inexpensive way to produce well-coated iron nanoparticles. The particles thus obtained present a much stronger magnetic response than any composite material produced up to now involving magnetic nanoparticles encapsulated in inorganic matrices, and the rich chemistry and easy functionalization of the silica outer surface make them promising materials for their application as magnetic carriers.
Researchers from the Martin Research Group at the University of Michigan have demonstrated they can precisely release individual drugs and bioactive molecules at desired points in time by using electrical stimulation of nanotubes.
A new fabrication technique involving an electrospray can create hemispherical nanocomposite cups with diameters as small as 50 nm.
