Melamine is a nitrogen-rich chemical that has received much attention in recent years owing
to a series of highly publicized food safety incidents. It is purposely added to foods by …

Food analysis plays a critical role in assessing human health risks and monitoring food
quality and safety. Currently, there is a pressing need for a reliable, portable, and quick …

A simple and label-free electrochemical aptasensor for bisphenol A (BPA) determination
was developed based on gold nanoparticles dotted graphene (GNPs/GR) nanocomposite …

A novel and simple sensor is developed in this paper for melamine detection, which is
based on an electropolymerized molecularly imprinted polymer (MIP) of para-aminobenzoic …

Based on the unique electronic properties and high adsorption capacity of carbon
nanotubes as well as the electrostatic attraction between protonated melamine and …

The consumption of melamine and urea contaminated cow milk causes indigestion, acidity,
ulcers and kidney stones in humans. In this context, a highly sensitive acetylcholinesterase …

Branched polyethyleneimine functionalized reduced graphene oxide (BPEIGn) was
prepared by a one-step reaction, catalyzed by NaOH, using branched polyethyleneimine …

Here, we report a simple and sensitive colorimetric method for detection of melamine in milk
using gold nanoparticles (AuNPs). AuNPs of 21-nm size were synthesized by the citrate …

The purpose of this paper is to develop a sensitive and low-cost colorimetric method for
detection of melamine using simple circuitry. The stable p-nitroaniline-modified silver …

A glassy carbon electrode modified with poly (alizarin red)/electrodeposited graphene
