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 ...

Gold–Oligonucleotide Nanoconstructs Engineered to Detect Conserved Enteroviral Nucleic Acid Sequences

open access: yesBiosensors, 2021
Enteroviruses are ubiquitous mammalian pathogens that can produce mild to life-threatening disease. We developed a multimodal, rapid, accurate and economical point-of-care biosensor that can detect nucleic acid sequences conserved amongst 96% of all ...

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

Ultra-Trace Protein Detection by Integrating Lateral Flow Biosensor with Ultrasound Enrichment

open access: yesAnalytical Chemistry, 2021
Lateral flow biosensor (LFB) is one of the most successful and applied commercial detection methods for food safety, drug abuse, and disease. Here, we integrated the ultrasound enrichment as sample preparation with LFB to achieve the ultra-trace protein detection in blood. When the ultrasound field is applied, the interaction between the acoustic field
