![]() ![]() The high-resolution electron microscopy images obtained have allowed us for the first time to directly visualize the internal structure of the Fd3 m nanoparticles and resolve the two different-sized inverse micelles that make up the structural motif within the Fd3 m unit cell, which upon structural analysis reveal excellent agreement with theoretical geometrical models. Copies of electronic files of this Technical Standard may be obtained from the DOE Office. We validate the internal symmetry of the nanoparticles using small-angle X-ray scattering and cryogenic transmission electron microscopy. When the pH is ≤6, the nanoparticles change from a compartmentalized to an accessible porous internal structure based on a 2D inverse hexagonal phase (plane group p6 mm). At pH 7.4, the nanoparticles have an internal structure consisting of discontinuous inverse micellar “aqueous pockets” based on space group Fd3 m. ![]() ![]() Here we have engineered highly sensitive lyotropic liquid crystalline nanoparticles that reversibly respond to changes in pH by altering the connectivity within their structure at physiological temperatures. Software yang satu ini sangat berguna untuk anda yang ada di bidang elektronika. The naturally occurring pH gradients found throughout the body make pH an attractive stimulus for guiding the response of a nanocarrier to specific locations or (sub)cellular compartments in the body. There is a growing demand to develop smart nanomaterials that are structure-responsive as they have the potential to offer enhanced dose, temporal and spatial control of compounds and chemical processes. ![]()
