AI Article Synopsis

  • A mathematical model for a peroxidase-based optical biosensor was developed using non-linear reaction-diffusion equations focusing on two compartments: an enzyme layer and an outer diffusion layer.
  • The digital simulation employed a finite difference technique to analyze the biosensor's performance.
  • Results indicated that both substrate concentration and the thickness of the enzyme and diffusion layers significantly affected the biosensor’s response, revealing complex kinetics at low concentrations of peroxidase and hydrogen peroxide.

Article Abstract

The response of a peroxidase-based optical biosensor was modelled digitally.A mathematical model of the optical biosensor is based on a system of non-linear reaction-diffusion equations. The modelling biosensor comprises two compartments, an enzyme layerand an outer diffusion layer. The digital simulation was carried out using finite differencetechnique. The influence of the substrate concentration as well as of the thickness of both theenzyme and diffusion layers on the biosensor response was investigated. Calculations showedcomplex kinetics of the biosensor response, especially at low concentrations of the peroxidaseand of the hydrogen peroxide.

Article Synopsis
  • The traditional biocatalytic precipitation (BCP) method has limitations due to HO's tendency to self-decompose, affecting its effectiveness in quantitative analysis.
  • Researchers discovered that a bimetallic single-atom catalyst (Co/Zn-N-C SAC) can activate dissolved oxygen to create reactive oxygen species, leading to improved detection methods.
  • The development of a new oxygen-activated photoelectrochemical (PEC) biosensor for chloramphenicol (CAP) detection demonstrates enhanced stability and accuracy by using Co/Zn-N-C SAC and cesium platinum bromide nanocrystals (CsPtBr NCs) without needing external reactants.

Semiconductor magic-sized nanoclusters (MSCs) possess atomic-level compositional precision and ultrasmall dimensions, allowing accurate modulation of electrochemiluminescence (ECL) properties, essential for advanced bioanalytical applications. However, low intrinsic ECL intensity and poor stability in bipolar electrode (BPE)-ECL systems hinder their broader use. In this work, we addressed these limitations through doping and direct optical crosslinking strategies, achieving a 24-fold boost in the ECL signal and a fivefold stability increase for doped (CdS):Ag MSCs compared with original (CdS) MSCs.

With the increasing incidence of thyroid cancer worldwide and the increasing demand for surgery, the risk of parathyroid injury is also increasing, which will lead to postoperative hypoparathyroidism (HP) and hypocalcemia. In order to improve the quality of life of patients after surgery, there is an urgent need to develop a novel platform that can identify the parathyroid gland immediately during surgery. The parathyroid gland promotes the increase of blood calcium concentration by secreting parathyroid hormone (PTH).

In this paper, we quantitatively compare the autofluorescence of stoichiometric low pressure chemical vapor deposition (LPCVD) silicon nitride and sputtered tantalum pentoxide waveguides at a pump wavelength of 532 nm. Through a direct quantitative characterization of comparable waveguides formed from the two films, we find no observable autofluorescence for tantalum pentoxide waveguides. Our experimental sensitivity is limited by Raman scattering of the pump into our detection band and our measurements indicate that the autofluorescence of the tantalum pentoxide waveguides is more than 600 × smaller than that of silicon nitride waveguides.

Putrescine is a kind of physical diamine that is closely related to food deterioration and food quality safety. This study employs a novel fiber optic biosensor based on S-tapered and waist extension techniques, as well as localized surface plasmon resonance (LSPR), to detect putrescine accurately. The gold nanoparticles (AuNPs) are fixed on the fiber to excite LSPR.
