The voltammetric behaviour of synthetic food colourant, amaranth, was studied using a multiwalled carbon nanotube (MWCNT) thin film-modified gold electrode in 0.1 M acetate buffer solution of pH 5.0.… Expand
A voltammetric sensor for acetaminophen based on electropolymerized-molecularly imprinted poly(o-aminophenol) modified gold electrode.
A simple and reliable molecularly imprinted polymer (MIP) based voltammetric sensor has been proposed for the determination of acetaminophen (AP). Gold nanoparticles (AuNPs) were initially deposited… Expand
Voltammetric determination of sulfamethoxazole at a multiwalled carbon nanotube modified glassy carbon sensor and its application studies.
Sulfamethoxazole (SMX) is an anti-bacterial sulfonamide. It prevents the formation of dihydrofolic acid, a compound that bacteria need in order to survive. The present work details the voltammetric… Expand
Differential pulse voltammetric determination and catalytic oxidation of sulfamethoxazole using [5,10,15,20- tetrakis (3-methoxy-4-hydroxy phenyl) porphyrinato] Cu (II) modified carbon paste sensor.
Sulfamethoxazole (SM) is a sulfonamide bacteriostatic antibiotic. Its primary activity is against susceptible forms of streptococcus, staphylococcus aureus, escherichia coli, haemophilus influenzae,… Expand
