Article Abstract
Recently, several studies have examined possible applications of nanoparticles for the development of electronic and optical sensors. The plasmon absorbance of gold nanoparticles has been used extensively to study biomolecular processes, including nicotinamide adenine dinucleotide/nicotinamide adenine dinucleotide phosphate-dependent enzymatic reactions. In this report, we describe the development of gold nanoparticles as a new colorimetric and sensitive detection method of glucose-6-phosphate dehydrogenase deficiency by means of controlled reversible assembly of gold nanoparticles. 3-nm polyvinylpyrrolidone/N,N'-dimethylaminopyridine-stabilized gold nanoparticles were synthesized, characterized and applied for an in vitro activity assay of 11 recombinant human glucose-6-phosphate dehydrogenase variants. Differences in the activity of the glucose-6-phosphate dehydrogenase variants from different deficiency classes were readily detected using the synthesized gold nanoparticles. The developed method can be easily distinguished with color change by naked eye for the detection of glucose-6-phosphate dehydrogenase deficiency. Moreover, we are the first to propose the segregation mechanism of polyvinylpyrrolidone/N,N'-dimethylaminopyridine-stabilized gold nanoparticles by reduced nicotinamide adenine dinucleotide phosphate. The method enables visual detection of glucose-6-phosphate dehydrogenase deficiency, which could be further developed for diagnostic testing of glucose-6-phosphate dehydrogenase deficiency.

Introduction: Breast cancer, a formidable global health challenge for women, necessitates innovative therapeutic strategies with enhanced efficacy and minimal side effects. Aripiprazole (ARI), a widely used schizophrenia medication, exhibits promising potential in the treatment of breast cancer. As cancer therapy evolves towards a combination approach, multimodal nano-based delivery systems, such as ARI-loaded niosomes (NIOs) combined with Chitosan-Au nanoparticles for chemo-photothermal therapy, show promise over traditional chemotherapy alone by enhancing targeted efficacy and minimizing side effects.

The present study introduces a minimalistic and cost-effective approach to synthesising Gold nanoparticles (AuNPs) using aqueous leaf extracts of Andrographis paniculata. In this synthesis, bioactive metabolites in the leaf extract act as reducing agents, converting Au³⁺ ions to metallic Au⁰, while proteins in the extract form a stabilising layer around the nanoparticles to prevent agglomeration and maintain particle size stability. The synthesised AuNPs were systematically characterised using a range of analytical techniques.

Here, we present three-dimensional-printed dual-channel flow-through miniaturized devices (3D) with dual electrochemical detection (ED) integrating two working electrodes each in an in-channel configuration (3D-ED). Prussian Blue (PB) shell-gold nanoparticles ((PB)AuNP) core-based electrochemistry was chosen for selective hydrogen peroxide determination. 3D-ED devices exhibited impress stability, identical intrachannel and interchannel electrochemical performances, and excellent interdevice precision with values under 9%, revealing the reliability of the design and fabrication of the devices.

Nanogold is an emerging material for enhancing surface-enhanced Raman scattering (SERS), which enables the detection of hazardous analytes at trace levels. This study presents a simple, single-step plasma synthesis method to control the size and yield of Au nanoparticles by using plasma-liquid redox chemistry. The pin-based argon plasma reduces the Au precursor in under 5 min, synthesizing Au spherical particles ranging from ∼20 nm at 0.

Nanoparticles have been of significant interest in various biomedical domains such as drug delivery, gene delivery, cytotoxicity analysis, and imaging. Despite the synthesis of a variety of nanoparticles, their cellular uptake efficiency remains a substantial obstacle, with only a small fraction of delivered nanoparticles (NPs) have been reported to traverse the cell membrane within 24 h. Consequently, higher doses are often necessitated, leading to increased toxicity concerns.
