The quality of food is fundamentally based on biochemical composition of food. Therefore, this review summarizes recent advances in the fabrication of different types of Biosensors that have been designed for the measurement of various components in the horticultural samples. We review various biosensors ranging from electrochemical, calorimetric, optical, immunosensors to screen-printed three ...

Thick-film screen printed silver-silver chloride (Ag/AgCl) reference electrodes have been fabricated and investigated as an alternative to liquid electrolyte Ag/AgCl reference electrodes. The performance of the electrodes was examined with variations of the potassium chloride (KCl) concentration in the final (top) layer of the electrode. Also, different types of binder (glass and polymer) were ...

A sensitive electroanalytical method for determination of acetaminophen (ACT) in paracetamol tablet has been developed and validated. Cyclic voltammetry (CV) was used to study the electrochemical behaviour of paracetamol, while differential pulse voltammetry (DPV) was used to determine ACT. Screen printed carbon electrode was used for the analysis. Determination of all parameters in paracetamol...

The glucose biosensors were prepared by the electropolymerization of the non-conductive polymer, Poly(o-phenylenediamine), onto a planar screen-printed electrode. A fabrication procedure was performed to decrease the waste of expensive enzyme. The amperometric glucose response was measured by the potensiostating of the prepared glucose biosensors at a potential of 0.3 V with ferrocene as mediat...

Urchin-like silver nanowires are prepared by reacting AgNO(3)(aq) with copper metal in the presence of cetyltrimethylammonium chloride and HNO(3)(aq) on a screen-printed carbon electrode at room temperature. The diameters of the nanowires are about 100 nm, and their lengths are up to 10 μm. Using Raman spectroscopy, the detection limit of Rhodamine 6G (R6G) on the urchin-like silver nanowire su...

Herein, we report the environmental impact quantification of a newly developed fully printed electrochemical device to assist colorimetric detection phosphate in saliva. The evaluation analytical procedure was performed according principles Green Analytical Chemistry and White Chemistry. standard method for relies on reaction between molybdate presence antimony potassium tartrate ascorbic acid,...

Acetylcholinesterase (ChE) sensor based on Prussian blue (PB) modified electrode was developed and tested for the detection of organophosphorus and carbamic pesticides. The signal of the sensor was generated in PB mediated oxidation of thiocholine recorded at +200 mv in DC mode. ChE from electric eel was immobilized by cross-linking with glutaraldehyde in the presence of bovine serum albumin (B...

An electrochemical immunosensor modified with the streptavidin/biotin system on screen printed carbon electrodes (SPCEs) for the detection of the dengue NS1 antigen was developed in this study. Monoclonal anti-NS1 capture antibody was immobilized on streptavidin-modified SPCEs to increase the sensitivity of the assay. Subsequently, a direct sandwich enzyme linked immunosorbent assay (ELISA) for...

Thrombin plays the role in cardiovascular diseases and regulates many processes in inflammation and could be a feature of many pathological conditions, including the thromboembolic disease, cancer and neurodegenerative diseases. An ultrasensitive and amplified electrochemical sandwich assay using screen-printed carbon electrode (SPCE) strips for thrombin detection was established in this study....
