Nanotechnology has developed as a ground-breaking field with enormous potential for a wide range of applications, including biotechnology, medicine, and environmental cleanup. One intriguing use is encasing bacteria in nanomaterials to improve and control their biological functions. In order to modify the biological functions of bacteria, various forms of nanomaterials are employed to encapsulate them. Through the goal of utilizing bacteria-encased nanoparticles for targeted drug delivery, bioremediation, and biotherapeutic interventions, researchers have been investigating various nanomaterials in recent years. Due to their changeable surface characteristics, metallic nanoparticles, such gold and silver nanoparticles, enable precise control over bacterial contact. Additionally, encapsulated bacteria benefit from the protective habitats provided by polymeric nanomaterials like liposomes, micelles, and hydrogels, which improves their survival and activity.

The use planned and the desired interaction with the bacteria that are enclosed influence the choice of nanomaterial. The viability and activity of encapsulated bacteria can be affected by a variety of encapsulation methods, including physical adsorption, covalent bonding, and layer-by-layer construction. Researchers may design novel systems that harness bacteria's biological activity for a variety of purposes by using the features of nanomaterials and improving encapsulation methods. To turn these encapsulation technologies into useful and secure applications, there are still issues to be solved, including as long-term stability, biocompatibility, and regulatory concerns. In conclusion, the integration of bacteria with nanomaterials opens up new avenues for manipulating their biological functions. As nanotechnology continues to evolve, the synergy between nanomaterials and encapsulated bacteria holds great promise for revolutionizing fields such as medicine, biotechnology, and environmental science.
