Microbial Biosensors: A Review

A microbial biosensor is an analytical instrument with a biologically integrated transducer that provides a quantifiable signal indicating the analytic concentration. This approach is suitable for analysing extracellular substances and the environment, as well as for metabolic sensory control. Although microbial biosensors show potential for use in a variety of detecting applications, they have certain limitations. Although microbial biosensors show potential for use in a variety of detecting domains, significant drawbacks remain, including poor selectivity, limited sensitivity, and impractical mobility. Microbial biosensors have been combined with various newly emerging micro/nanotechnologies and utilised to a wide range of detection applications to overcome such restrictions. This review article examines micro/nanotechnologies that have been combined with microbial biosensors and highlights current developments and applications that have resulted from such innovative integration. Future perspectives on the integration of micro/nanotechnologies with microbial biosensors will be explored, as will the essential advances and enhancements.
