Here we propose an electrochemical aptamer-based sensing strategy for sensitive detection
of the codeine (COD). Platform construction was started by decoration NH 2-functionalized …

A “signal-on” electrochemical aptasensor was proposed by employing hollow cubic
platinum@ gold nanoframes functionalized polyethyleneimine-reduced graphene oxide …

Organophosphorus pesticides (OPs) are one of the most frequently used pesticides in
agriculture, and their residues in environment have caused serious human health and …

Aptamer has been proved to be an important probe for antibiotic detection. Here, the
electrical signal was doubly amplified by the synergistic effect of C-WO 3 and AuNPs. The …

We proposed a multiplex electrochemical aptasensor based on a screen-printed carbon
electrode (SPCE), which was modified by carbon nanofibers (CNFs) and mesoporous …

The constant need of humans and animals for food resources was led to overuse of
antibiotics as vital medicines. In this regard, we are now facing major concern about the risks …

A novel label-free electrochemical aptasensor was fabricated based on a three-dimensional
porous electrode (3D-CS/rGO/GCE) for the detection of acetamiprid residues. The sensing …

In this paper, a novel aptamer sensor for kanamycin was prepared by using a
complementary DNA (cDNA) strand of kanamycin aptamer as sensor and horseradish …

The sensitive, selective, and accurate analysis of kanamycin (KAN), a common
aminoglycoside antibiotic, is vital to ensure human health and food safety. Here, a well …

In this work, a novel ultrasensitive aptasensor for deoxynivalenol (DON) detection based on
the polyethyleneimine-functionalised porous reduced graphene oxide loaded gold …
