Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Inverse Scattering Method Design of Regrowth-Free Single-Mode Semiconductor Lasers Using Pit Perturbations for Monolithic Integration

IEEE Photonics Journal, 2018
An inverse scattering method is used to design regrowth-free single-mode lasers, using etch depth insensitive pits as perturbations in the laser cavity. These pit perturbations are circular holes etched into the waveguide of each laser to a depth 0.8$\mu
