Researchers have built a setup for recording holograms of tiny objects like living cells with a femtosecond speed. The new method allows one to reconstruct phase topography of a studied sample according to deformations that emerge in a laser pulse when it passes through the specimen.
Researchers have developed two pH-responsive nanoprobes to guide brain-tumor surgery via the magnetic resonance (MR) and surface-enhanced resonance Raman spectroscopy (SERRS) signals activated upon their self-assembly in acidic tumor extracellular fluid.
Inspired by suprabiomolecular assembly governed by stacking interactions, researchers have developed a versatile strategy to assemble nanoparticles of diverse sizes and compositions into nanoparticle pillars with tailorable internal nanoparticle configurations.
Researchers have demonstrated that it is possible to confer antimicrobial activity to gold nanoparticles, which have long been considered as inert, by way of controlling their sizes to the nanocluster range.
Scientists have developed a new optical microprobe able to control brain electrical activity by projecting light on wide volumes or selected portions of the central nervous system in an very controlled fashion.
