Researchers use 3D bioprinting to create eye tissue

Dec 23, 2022 (Nanowerk News) Scientists used patient stem cells and 3D bioprinting to produce eye tissue that will advance understanding of the mechanisms of blinding diseases (Nature Methods, "3D outer retina barrier uncovers RPE-dependent choroidal phenotype in advanced macular degeneration"). The research team from the National Eye Institute (NEI),...

At the edge of graphene-based electronics

Dec 22, 2022 (Nanowerk News) A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But its potential faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to...

Collective circular dichroism by chiral plasmonic nanoparticles

Dec 22, 2022 (Nanowerk News) Molecular chirality means the geometrical property of molecules with broken mirror symmetry. Characterizing molecular chirality and understanding their roles in physiochemical situations has been important in broad research scope such as, biology, chemistry, and pharmaceutics. In general, molecular chirality can be analyzed using circular dichroism...

Charge density distributions of electric double layers

Dec 22, 2022 (Nanowerk News) Expanding on their recently developed electrochemical 3D atomic force microscopy (EC-3D-AFM) technique, University of Illinois Urbana-Champaign researchers have derived the depth profile of the charge density of electric double layers (EDLs). Through statistical analysis, peak deconvolution, and electrostatic calculations, the researchers developed charge profiling 3D...
