Preparation and characterisation of NH gas sensor based on nanocomposite.

was synthesised by the process. The produced powders were characterised by , , , , and tests. The sensors' function was based on with thin film deposited on top of interdigitated electrodes ().

A simple optical pH sensor based on pectin and L-derived anthocyanin for fish freshness monitoring.

A simple optical pH sensor using the active compound anthocyanin (ACN), derived L. flower immobilized in a pectin membrane matrix, was been fabricated and employed to monitor the freshness of tilapia fish at room temperature and 4 C storage. The quantitative pH values were measured based on the UV-Vis spectroscopy absorbance.

Optical pH Sensor Based on Immobilization Anthocyanin from L. onto Polyelectrolyte Complex Pectin-Chitosan Membrane for a Determination Method of Salivary pH.

A simple optical pH sensor based on immobilization, L. anthocyanin methanol extract, onto a pectin-chitosan polyelectrolyte complex (pectin-chitosan PEC), has been successfully fabricated. The optical pH sensor was manufactured as a membrane made of pectin-chitosan PEC and the extracted anthocyanin.

Synergy Effect of Nanocrystalline Cellulose for the Biosensing Detection of Glucose.

Integrating polypyrrole-cellulose nanocrystal-based composites with glucose oxidase (GOx) as a new sensing regime was investigated. Polypyrrole-cellulose nanocrystal (PPy-CNC)-based composite as a novel immobilization membrane with unique physicochemical properties was found to enhance biosensor performance. Field emission scanning electron microscopy (FESEM) images showed that fibers were nanosized and porous, which is appropriate for accommodating enzymes and increasing electron transfer kinetics.

Synthesis and application of polypyrrole/carrageenan nano-bio composite as a cathode catalyst in microbial fuel cells.

A novel nano-bio composite polypyrrole (PPy)/kappa-carrageenan(KC) was fabricated and characterized for application as a cathode catalyst in a microbial fuel cell (MFC). High resolution SEM and TEM verified the bud-like shape and uniform distribution of the PPy in the KC matrix. X-ray diffraction (XRD) has approved the amorphous structure of the PPy/KC as well.
