Pesticide residues are distinguished by high levels of environmental persistence and
toxicity to both humans and animals. Several farmers utilize various pesticides, including
organophosphate insecticides, and malathion is among the most used pesticides. In this
study, the researchers used egg yolk powder carbon quantum dots (EYP CQDs) to detect
pesticide residues in eggplant fruit by synthesizing a commercially available egg yolk
powder using a hydrothermal method, water extraction, dialysis, and filtration. The
prepared nanomaterial was chara.cterized based on their morphology, chemical and optical
properties, and stability using microscopy and spectrophotometry equipment. The EYP
CQDs showed bright blue fluorescence under UV light at 350 nm wavelength and were
used to detect trace concentrations of malathion pesticides by its fluorescence quenching.
In a small amount of volume, EYP CQDs showed fluorescence quenching properties in
different malathion concentrations, which proved that the synthesized nano-sensor is
sensitive. Furthermore, it can be a good sensor for environmental and food safety
monitoring.
