Scientists at Yale University have designed and tested a drug delivery system that shows early promise for improved treatment of lupus and other chronic, uncured autoimmune diseases, such as multiple sclerosis and Type 1 diabetes.
The salinity difference between fresh water and salt water could be a source of renewable energy. However, power yields from existing techniques are not high enough to make them viable. A solution to this problem may now have been found. Researchers have discovered a new means of harnessing this energy: osmotic flow through boron nitride nanotubes generates huge electric currents, with 1,000 times the efficiency of any previous system.
Nanoparticles filled with a drug could be a new tool for treating cancer in the future. A new study shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumour cells - and how they can be given properties to make them visible in MR scanners and thus rendered trackable.
According to Finnish-Estonian joint research with data obtained on two crustacean species, there is apparently no reason to consider silver nanoparticles more dangerous for aquatic ecosystems than silver ions.
At the Faculty of Pharmacy of the Basque Public University, the Pharmacokinetics, Nanotechnology and Gene Therapy research team is using nanotechnology to develop new formulations that can be applied to drugs and gene therapy. Specifically, they are using nanoparticles to design systems for delivering genes and drugs; this helps to get the genes and drugs tothe point of action so that they can produce the desired effect.
The Eli and Britt Harari Graphene Enterprise Award will help establish further enterprises in graphene at the University. The GBP 50,000 award aims to encourage the development of an entrepreneurial culture across the University's doctoral and postdoctoral research base.
Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience in our daily lives.
In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.
The newly-developed double switchable membranes could make it possible, in future, to filter different biomolecules, e.g. hormones, proteins, nucleic acids (DNA), according to pore size. This opens up a further possible field of application, in addition to water purification, in the field of medicine e.g. for blood purification.
Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.
