Fluorescent semiconductor quantum dots.

The researchers assess this emerging field and highlight two recent advances in the 28th January 2005 issue of the peer-reviewed journal Science. Undoubtedly, QDots lived as biological probes up to the hopes of their initial promoters,’said the article ‘s senior author, Shimon Weiss, a Jonsson Cancer Center researcher, UCLA professor of chemistry, biochemistry and physiology and a member of of the University of California NanoSystems Institute . ‘This paper presents an objective point of view and perspective of what we are doing now and what we might be able in the future. Undoubtedly, biologists are beginning to see these exciting developments and yet unforeseen applications for this new physiology toolkit, enhancing their existing arsenal of imaging Tools ‘.. Fluorescent semiconductor quantum dots, or qdots promise for high-resolution cellular imaging and the long-term observation of individual molecules and their movement within cells after a UCLA-led team from chemistry and biochemistry researchers, scientists comprises of Stanford University.

Quantum dots are much more resistant to degradation than other optical imaging probes, follow follow cellular processes for a long time and shed new light on molecular interactions also, because they are nanocrystals. Small boulders big one billionth of a meter. Qdots a good contrast for imaging with an electron microscope Based on recent advances in UCLA laboratories, the researchers hope.. Qdot molecular imaging is a new way of seeing biological processes at work in the cells and in small animals. Probes can be attached to a particular protein or receptor to monitor it, and to see how other molecules in other molecules in interaction, which is part of the cell and which, in signaling pathways, the protein can be used to perform normal cell functions and abnormal functions , which may have resulted in use cancer.A 2002 77 per cent of 77 % the childless male cancer patients aged 14 to 40, they would would like to father children in the future in, write it down. Survey was only half of these were given the possibility to the spermatozoa bank, and less than a quarter been done so effectively.
