An efficient method to investigate the window size of the silica shell generated via the classical Stöber method is reported by making use of the unique aggregation-induced emission property of Au(I)-thiolate complexes, which can precisely probe the porosity of the silica shell in Au(I)-thiolate@SiO nanoparticles.

Protein-nanoparticle interactions and the resulting corona formation play crucial roles in the behavior and functionality of nanoparticles in biological environments. In this study, we present a comprehensive analysis of protein corona formation with superfolder green fluorescent protein (sfGFP) and bovine serum albumin in silica nanoparticle dispersions using small-angle X-ray scattering (SAXS) and dynamic light scattering (DLS). For the first time, we subtracted the scattering of individual proteins in solution and individual nanoparticles from the protein-nanoparticle complexes.

Aptamer-Conjugated Multi-Quantum Dot-Embedded Silica Nanoparticles for Lateral Flow Immunoassay.

Biosensors (Basel)

January 2025

Department of Bioscience and Biotechnology, Konkuk University, Seoul 05029, Republic of Korea.

Lateral flow immunoassays (LFIAs) are widely used for their low cost, simplicity, and rapid results; however, enhancing their reliability requires the meticulous selection of ligands and nanoparticles (NPs). SiO@QD@SiO (QD) nanoparticles, which consist of quantum dots (QDs) embedded in a silica (SiO) core and surrounded by an outer SiO shell, exhibit significantly higher fluorescence intensity (FI) compared to single QDs. In this study, we prepared QD@PEG@Aptamer, an aptamer conjugated with QD using succinimidyl-[(N-maleimidopropionamido)-hexaethyleneglycol]ester, which is 130 times brighter than single QDs, for detecting carbohydrate antigen (CA) 19-9 through LFIA.

Graves' disease (GD) is an autoimmune disorder with a high incidence rate, particularly affecting women of reproductive age. Current treatment modalities for GD carry significant disadvantages, especially for pregnant or nursing women. As a novel extracorporeal therapeutic technique, high-intensity focused ultrasound (HIFU) shows great promise for treating GD; however, its low treatment efficacy impedes clinical application.

In this study, we present an ultrasensitive and specific multiplexed detection method for SARS-CoV-2 and influenza (Flu) utilizing CRISPR/Cas13a technology combined with a hydrogel-encapsulated photonic crystal (PhC) barcode integrated with hybridization chain reaction (HCR). The barcodes, characterized by core-shell structures, are fabricated through partial replication of periodically ordered hexagonally close-packed silicon dioxide beads. Consequently, the opal hydrogel shell of these barcodes features abundant interconnected pores that provide a substantial surface area for probe immobilization.
