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 […]
