One million quality factor integrated ring resonators in the mid‐infrared

Nanophotonics, Volume 14, Issue 7, Page 1009-1015, April 2025.
Abstract We report ring resonators on a silicon germanium on silicon platform operating in the mid‐infrared wavelength range around 3.5–4.6 µm with quality factors reaching up to one million. Advances in fabrication technology enable us to demonstrate such high Q‐factors, which put silicon germanium at the forefront of mid‐infrared integrated photonic ...

Glepaglutide‐Loaded Foam for the Induction of Mucosal Healing in the Treatment of Inflammatory Bowel Disease

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Glepaglutide (GL), a GLP‐2 analog with an extended half‐life (50 h), is currently undergoing clinical trials for patients with short bowel syndrome. GL requires subcutaneous injection, which poses challenges for potential patient compliance. To address this challenge, we loaded GL into a rectal foam formulation using CO2 as a permeation enhancer to ...
