New catheter lets doctors see inside arteries for first time

October 5, 2016

A new safer catheter design that allows cardiologists to see inside arteries for the first time and remove plaque from only diseased tissue has been used by interventional cardiologists at UC San Diego Health. The new image-guided device, Avinger’s Pantheris, allows doctors to see and remove plaque simultaneously during an atherectomy — a minimally invasive … more…

Genetically engineered peptides on 2D nanosheets form bio-nano interfaces

October 4, 2016

A first step towards future self-assembled solid-state biomedical and electro-optical nanodevices Engineers at the University of Washington have created genetically engineered peptides that self-assemble into arrays of nanowires on two-dimensional nanosheets (single-layer graphene and molybdenum disulfide) to relay information across a bio-nano interface — a first step towards fully self-assembled future biomedical and electro-optical bionanoelectronic devices. Arrays of peptides could provide organized scaffolds for functional biomolecules, … more…
