Image Credit: Digital Surf Nanoparticles find their use in numerous everyday commercial products, including cosmetics, foods and pharmaceuticals. Their characterization at the nanometer scale requires  very particular capabilities . For this specific application, a team of researchers at the LNE Nanotech Institute (France) synthesized measurements from multiple instrument techniques, including Scanning Electron Microscopy (SEM) equipped with a next-generation energy dispersive X-ray detector (EDX) and Atomic Force Microscopy (AFM) . Advanced processing software was necessary in order to c...

Housing and Development Newsletter In particular, it could work on biological samples in water, opening the door to what has become a huge area of current biological and biomedical research: AFM of biological processes to understand things such as the mechanism of action of antimicrobial peptides. It is the highest resolution microscopy available for biological samples in water, other than that of another technology he co-invented, called Scanning Ion Conductance Microscopy (SICM). SICM is more difficult to use than AFM and so, thus far, is only used by specialists. He collaborated with fello...

Nanotechnology Now Paul Hansma Photo Credit: COURTESY IMAGE Abstract: Necessity is the mother of invention, and nowhere does that aphorism apply more than in the realm of humans and their physical needs. Building Useful Gadgets: Biophysicist Paul Hansma joins the National Academy of Inventors Santa Barbara, CA | Posted on December 9th, 2020 That need has inspired Paul Hansma, a UC Santa Barbara biophysicist, to devote decades of his career to developing instruments that can advance medicine in the diagnosis and treatment of some of the most debilitating conditions, thereby improving human hea...
