Good ideas can develop when people cooperate, and work together as a whole towards a common cause by openly exchanging ideas and view points. As a Molecular Biologist, I am bringing in a certain view. But it is at the intersection of one discipline with others where many new innovative ways of thinking are born. For this reason, this site will henceforth be a collaborative-community effort in which we at the "Bio-Based" community will bring you news and views of things that could make this world a better place. In the coming days and weeks, look forward to contributions from my dear friends and colleagues who share the common vision of moving humanity forwards with innovative thinking and action.
With my thesis defense coming up this Monday, I really did not have as much time to share all the interesting things I came across lately. But I did not want to miss the chance to make a quick note to myself and the readers of this site of an interesting paper, titled "DNA-based programming of quantum dot valency, self-assembly and luminescence" just published in Nature Nanotechnology . Grigory Tikhomirov et al. report "the self-assembly of quantum dot complexes using cadmium telluride nanocrystals capped with specific sequences of DNA. Quantum dots with between one and five DNA-based binding sites are synthesized and then used as building blocks to create a variety of rationally designed assemblies, including cross-shaped complexes containing three different types of dots...Through changes in pH, the conformation of the complexes can also be reversibly switched, turning on and off the transfer of energy between the constituent quantum dots." In other w...
