A new ultra-high resolution 'nanoscope' is capable of taking 3-D images of an entire cell and its cellular constituents in unprecedented detail, an advance that could reveal biological phenomena never before seen and bring new medical insights.
Researchers have shown that zinc oxide quantum dots prepared by an original method developed by them, after modification by the click reaction with the participation of copper ions, fully retain their ability to emit light.
Scientists have visualised a molecular machine called the APC/C. APC/C initiates chromosome segregation and it does this only after the mother cell has completed all other steps that are necessary for cell division.
For years scientists and dieticians have argued over the health benefits of dietary fat. Research published this week, however, shows that piggybacking onto natural fat absorption pathways can dramatically enhance the utility of some drugs.
In a set of studies in mice bearing human tumors, nanoparticles designed to bind to a protein called P-selectin successfully delivered both chemotherapy drugs and targeted therapies to tumor blood vessels.
