Abstract A new method was developed to quickly produce carboxymethyl hemicellulose (CM-Hemi) and fluorescent nitrogen-doped carbon dots (N–CDs) from sugarcane bagasse (SB). These materials were then combined with calcium chloride (CaCl₂) create hydrogel sensors antibacterial antifungal properties. The CM-Hemi@Ca-N–CDs effective against both Gram-negative ( Escherichia coli ) Gram-positive Staphylococcus aureus bacteria compared CM-Hemi@Ca which give no activity. Both hydrogels also exhibited properties Candida albicans . Molecular docking studies revealed that the had strong binding interactions protein (1.92 A°) compard (2.01 A°), aligned inhibition zone measurements test. fluorescence microscope differences in emitted light color when interacted different types of microorganisms, likely due variations their cell walls. Density functional theory (DFT) calculations indicate incorporation N–CDs into enhances its stability rigidity. This is evidenced by lower energy gap (E g ), higher electron affinity (μ), softness (S) hydrogel. Additionally, formation amide bonds between CM-Hemi contributes increased rigidity hydrogel.These findings supporting th effectiveness as an antibacterial/antifungal sensor.
