The g-C3N4/CS biosensor was designed, fabricated, and tested using compounds such as glucose, urine, lactose, flutamide at a molarity of 10 µM, which could demonstrate high sensitivity 200 μm-1 for flutamide. Powerful effective medium theory FDTD simulation were used to predict the most favorable mode plasmonic properties graphite carbon nitride chitosan nanocomposite. research also explores characteristics surface plasmon resonance exhibited by nanocomposite content is adjusted. Subsequent simulations are conducted on nanocomposites incorporating thin layer modified gold structure. intricate ultimately reveal optimal combination, under three different pH conditions (6.2, 7.2, 8). In acidic conditions, kinetic profile yielded KD= 3.45 × 10−7, surpassing KD value film. Au significantly outperformed alternative material. demonstrated linear behavior across wide concentration range from 1 150 achieving detection limit 120 nM with its sensitivity.
