A flexible cotton-based Ag/AgPO/MXene (APMX) ternary composite material was successfully synthesized, serving as a dual-function and reusable surface-enhanced Raman scattering (SERS) substrate for both sensitive detection and efficient organic dye degradation. The remarkable SERS properties of the composite can be attributed to the combined effects of electromagnetic enhancement by Ag nanoparticles (Ag NPs), charge transfer enhancement from AgPO, and the chemical enhancement mechanisms associated with MXene. When employed for the detection of crystal violet (CV), the material exhibits outstanding sensitivity, achieving a limit of detection (LOD) as low as 3.82 × 10 M. Moreover, the synergistic effects between the localized surface plasmon resonance (LSPR) of Ag NPs and the high electrical conductivity of MXene significantly improve charge transfer on the AgPO surface, thereby enhancing photocatalytic efficiency. Under visible light irradiation, the composite achieves an 83.64 % degradation rate of CV within 90 min. By integrating the composite material onto cotton, its flexibility and practical applicability are enhanced, allowing for in-situ SERS detection and effective analysis on irregular surfaces. Additionally, the photocatalytic degradation function imparts a self-cleaning property, greatly improving its reusability and sustainability. As a high-performance, dual-function material, the APMX cotton shows great potential in environmental monitoring and pollution control by providing sensitive SERS detection and efficient wastewater pollutant degradation.

In this study, a novel cellulose-derived support of amino-functionalized cellulose beads (ACBs) for laccase immobilization was successfully developed using cellulose beads (CBs) and polyethyleneimine by glutaraldehyde crosslinking reaction. The covalent immobilization of laccase on ACBs was achieved via a Schiff base reaction. The obtained enzyme catalysts (Lac-ACBs) were applied for simultaneous adsorption and enzymatic conversion of tetracycline (TC) from water.

The residues of pesticides and antibiotics have always been a major concern in agriculture and food safety. In order to provide a new method for the rapid detection of organophosphorus pesticides and antibiotics, a novel Cd(II) chain-based zwitterionic metal-organic framework MOF 1 with high sensitivity fluorescence sensing performance was successfully synthesized. A series of researches showed that the water- and pH-stable bifunctional MOF 1 has a great ability to detect phosmet (PSM) and chlortetracycline (CTC) in water through fluorescence quenching effect, with high detection sensitivity, low detection limits (0.
