Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐

Advanced Materials Technologies, EarlyView.This study describes the fabrication of arrays of luminal tissue constructs for 3D luminal tissue modeling. An oil or media‐filled reservoir between constructs serves as a liquid barrier or bridge to regulate communication between lumens within the array for modeling multi‐tissue interactions in vitro. Abstract Cell‐lined luminal structures are crucial

Advanced Materials Technologies, EarlyView.Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.
