Salbutamol (SAL) is a substance harmful to human health and is banned as a growth promoter in livestock, prompting the need for its detection in meat and urine.
Researchers developed a competitive paper-based colorimetric immunoassay (PCI) using an Ag PO /Ag nanocomposite, which simplifies and cheapens the detection process while being sensitive and specific for SAL.
This new method is easy to fabricate with low-cost materials and requires only small amounts of samples and reagents, making it quicker and more efficient than traditional ELISA tests.
