| description | With the rapid development of modern science and technology and the diversification of social needs, traditional single-performance materials struggle to meet the complex and changeable application scenarios. To address the multifaceted requirements of biomedical applications, such as disease diagnosis and treatment, scientists are dedicated to developing new multifunctional biomaterials with multiple activities. Bi<sub>4</sub>Ti<sub>3</sub>O<sub>12</sub> (BTO), despite its versatility and application potential, has insufficient photocatalytic performance. Silver nanoparticles (Ag) and Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> are particularly effective as antibacterial materials but they have relatively single functions. In this study, BTO/Ag/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> biomultifunctional materials were constructed by combining BTO with Ag and Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>. We discovered that the addition of Ag and Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> effectively optimized the visible light absorption characteristics of BTO, reduced the electron transfer resistance, and increased the carrier concentration, thus significantly improving the photocatalytic performance of composite material, thereby markedly improving the composite’s photocatalytic performance and its efficacy in photochemical sensing and photodegradation. At the same time, BTO, as a carrier, effectively avoids Ag and Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> agglomeration and gives full play to its antibacterial properties. In the specific performance studies, ascorbic acid and MB were used as the subjects of photochemical sensing and photodegradation properties, while <i>Escherichia coli</i> and <i>Staphylococcus aureus</i> were tested for antibacterial properties. The BTO/Ag/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> composite showed remarkable results in all assessments, demonstrating its potential as a versatile antibacterial and photocatalytic material. |
