The importance of mesenchymal stem cells (MSC) in vascular regeneration is becoming increasingly recognized. However, few in vitro studies have been performed to identify the effects of environmental elasticity on the differentiation of MSC into vascular cell types. Electrospinning and photopolymerization techniques were used to fabricate a… (More)
Peptides are multifunctional reagents (reducing and capping agents) that can be used for the synthesis of biocompatible metal nanoparticles under relatively mild conditions. However, the progress in peptide synthesis of metal nanoparticles has been slow due to the lack of peptide design rules. It is difficult to establish sequence-reactivity relationships… (More)
Gold nanoparticles (AuNPs) are widely used as colorimetric probes for biosensing, relying on their unique particle size-dependent and/or interparticle distance-dependent extinction spectrum and solution color. Herein, we describe an AuNP-based colorimetric assay to detect binding interactions between nuclear hormone receptors and their corresponding… (More)
This paper reports a novel synthesis approach of bovine serum albumin (BSA) protein-templated ultrasmall (<2 nm) Ag nanocluster (NC) with strong singlet oxygen generation capacity for photodynamic therapy (PDT). An atomically precise BSA-Ag13 NC (i.e., 13 Ag atoms per cluster) is successfully synthesized for the first time by using NaOH-dissolved NaBH4… (More)
We have developed a unique metal nanoparticle (mNPs)-based assay to detect sequence-specific interactions between transcription factor and its corresponding DNA-binding elements. This assay exploits the interparticle-distance dependent optical properties of noble mNPs as sensing element and utilizes specific protein-DNA interactions to control the… (More)
Gold nanoclusters with five discrete sizes (Au4, Au8, Au10, Au13, and Au25) are synthesized in a protein template with predefined conformation via a CO-mediated synthesis.
We have developed a label-free homogeneous phase bioassay to characterize the DNA binding properties of single-stranded DNA binding (SSB) protein, a key protein involved in various DNA processes such as DNA replication and repair. This assay uses gold nanoparticles (AuNPs) as sensing probe and is based on the phenomenon that preformed SSB-single-stranded… (More)
A facile drug screening method based on synthesis of fluorescent gold nanoclusters inside albumin proteins loaded with small molecular drugs and comparing the relative fluorescence intensities of the resultant gold nanoclusters has been developed and successfully applied for the quantitative measurement of drug-protein binding constants.
Palm kernel expeller (PKE), the by-product derived from the palm kernel oil milling industry, is commonly added to ruminant feed as a source of protein. Recent research has demonstrated that the enzymatically hydrolyzed protein is inhibitory to spore-forming bacteria including Bacillus cereus. The trypsin-hydrolyzed PKE peptide appears to disrupt the… (More)
This study investigated the survival of encapsulated potential probiotic Lactobacillus plantarum which isolated from fermented cocoa beans. κ-Carrageenan was used to encapsulate the probiotic. Encapsulation techniques such as emulsification, freeze-drying or extrusion were adopted to encapsulate the probiotic. Freeze-drying and extrusion methods showed… (More)
