Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

open access: yesAdvanced 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‐

Quantitative Assessment of Gut and Vascular Barriers in TTOP, a Cartridge‐Based Bicompartmental Culture Platform

open access: yesAdvanced Materials Technologies, EarlyView.
The modular, versatile, and standardized cartridge‐based culture module allows to replicate gut and vascular barriers. Its conventional handling requirements facilitate adoption by non‐technical users, while the design allows safe manipulation and retrieval of samples for permeability assays and endpoint analysis.

Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine

open access: yesAdvanced Materials Technologies, EarlyView.
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.
