Scientists have come up with a new way to detect tiny amounts of sulfadiazine (SDZ) using a special nanopolypropylene surface. They created a molecularly imprinted polyacrylamide (PP@MIP) probe that works with a technique called Resonance Rayleigh Scattering (RRS). This probe helps to quickly and accurately spot SDZ, even in small quantities.
The scientists used nanopolypropylene as a base and sulfadiazine as a guide to make this probe. They also added acrylamide to help it work better. The probe's special power comes from how it interacts with gold nanoparticles (AuNP). When these nanoparticles are made, the probe helps to create more of them, which boosts the RRS signal. This makes it easier to detect SDZ.
The new method can find SDZ in amounts as small as 0. 004 nanomoles per liter. It works well within a range of 0. 0125 to 0. 150 nanomoles per liter. When tested in real samples, the method gave consistent results, with recovery rates between 93. 3 and 109. 9% and low error rates.
