Nanostructured WS₂@Chitosan-Modified Screen-Printed Carbon Electrodes for Efficient Amperometric Detection of Histamine.

ABSTRACT: Histamine, a pivotal chemical within certain cells of the human body, is responsible for eliciting various allergic symptoms, such as sneezing and a runny nose. In cases of allergies, where the immune system misidentifies typically harmless substances, such as certain foods or dust, as harmful, an efficient histamine sensor becomes imperative. This research introduces a novel sensing platform by employing a material comprising hydrothermally synthesized WS₂ nanosheets and using this with a chitosan (CS) biopolymer on a screen-printed carbon electrode (SPE). Integrating WS₂ and CS components on the SPE via drop-casting synergistically enhances conductivity and various sensor properties. This novel hybrid material combines organic CS and inorganic WS₂ compone
