Lipid bilayer formation
Shows the deposition of liposomes on to the surface of an optical chip and their subsequent rupture and merger to form a lipid bilayer. Protein molecules then embed and float in the surface of the bilayer. This is an excerpt from a video that iemedia solutions (http://www.iemedia.co.uk) produced for the Scientific Instrumentation Division of the [...]

Self-Assembling Nanoliter Containers
Nanotechnology, the new science of extreme miniaturization, is a rapidly growing field in engineering. On this size scale, it is extremely difficult and expensive to fabricate analogs of macroscale engineering, such as grippers. Drawing inspiration from biological fabrication in nature, engineers are seeking to self-assemble structures from the bottom up. This manufacturing paradigm has been [...]
Small nanotechnology has big impact – part 2
Researchers at Warwick University explain how the small scale world of nanotechnology is having a big impact on our everyday world, part two – cement and nano, amongst other things. Duration : 0:9:42

SDJA AP Biology DNA Lab
Professor Curt Wittenberg, a molecular geneticist at Scripps Research Institute and an SDJA parent, came in to do a lab with the students. They separated pieces of DNA using gel electrophoresis. The students learned how to calculate the sizes of DNA fragments based on the distances that they travel in the gel. It was a [...]
