Normalizing the Optical Signal Enables Robust Assays with Lateral Flow Biosensors

open access: yesACS Omega, 2022
Lateral flow assays (LFAs) are widely adopted for fast, on-site molecular diagnostics. Obtaining high-precision assay results, however, remains challenging and often requires a dedicated optical setup to control the imaging environment. Here, we describe quick light normalization exam (qLiNE) that transforms ubiquitous smartphones into a robust LFA ...

A Versatile, Portable Intravital Microscopy Platform for Studying Beta-cell Biology In Vivo [PDF]

open access: yes, 2019
The pancreatic islet is a complex micro-organ containing numerous cell types, including endocrine, immune, and endothelial cells. The communication of these systems is lost upon isolation of the islets, and therefore the pathogenesis of diabetes can only
