Researchers use lasers to grow biological tissue in the lab to produce microfilaments
Filament optical 3D bioprinters can be used to create aligned tissue structures. Credit: Zurich University of the Arts / Samuel Thalmann Pioneer Fellow Hao Liu uses lasers to generate microfilament structures to grow living tissue in the lab for research and medical purposes, from muscle tissue to cartilage. He is currently working on getting this technology ready for the market.…

Atomic-level engineering of perovskite materials opens the way to new lasers and LEDs
Graphical summary. Credit: Matter (2024). DOI: 10.1016/j.matt.2024.09.010 Researchers have developed and demonstrated a technique that can process a class of materials called layered hybrid perovskites (LHPs) down to the atomic level. This determines exactly how the material converts electrical charge into light. This technology opens the door to engineering materials for use in next-generation printed LEDs and lasers, and is…
