Biosensor: an emerging safety tool for meat industry

Abstract

The meat industry associated with the health hazards like deadly pathogens, veterinary drugs, pesticide residues, toxins and heavy metals is in need of a tool to tackle the awful situation and ensure safer product to consumer. The growth in the industry, global trade scenario, stringent laws and consumer awareness has placed an extra onus on the meat industry to meet out the expectations and demands. Biosensors are the latest tool of detection in the fast growing industries including the food industry. Hence an attempt is envisaged here to review the possibility of harnessing biosensors as tool of safety to safe guard the consumer health and address safety issues in reference to the common threats of concern in the meat industry.

An appraisal of various pathogen detection methods in eggs and poultry

“…There are two major components of any biosensors: a bioreceptor to recognize or sense the target analyte and a transducer to convert recognition into a quantifiable electrical signal. Hence, classification of biosensors can be done based on the kind of biocomponent used, mode or mechanism of signal transduction, etc., (Velusamy et al, 2010;Singh et al, 2016). The transduction elements are generally optical, piezoelectric, electrochemical and magnetoelastic and the recognition elements that are responsible for specificity can be enzymes, cell receptors, antigens, antibodies, aptamers, bacteriophages, nucleic acid probes and antimicrobial peptides (Bhunia, 2014).…”

Label-Free Ultrasensitive and Environment-Friendly Immunosensor Based on a Silica Optical Fiber for the Determination of Ciprofloxacin in Wastewater Samples

“…In order to reduce the use of toxic solvents, decrease the analysis time, and minimize costs, the use of biosensors is an effective option that can provide sensitive analytical responses. Biosensors are characterized by biological recognition using the response driven by an antigen, antibody, or enzyme . When antibodies are used, the biosensor is called an immunosensor, presenting high specificity due to the analyte–antibody bond …”

“…Biosensors are characterized by biological recognition using the response driven by an antigen, antibody, or enzyme. 31 When antibodies are used, the biosensor is called an immunosensor, presenting high specificity due to the analyte−antibody bond. 32 Immunosensors can be prepared using different materials.…”

Simple, fast and environmentally friendly method to determine ciprofloxacin in wastewater samples based on an impedimetric immunosensor

“…Biosensors convert a biological response from antibodies, antigens, nucleic acids or enzymes immobilized on the substrate into an electrical signal. 27 Biosensors that achieve the biological recognition using antibodies are called immunosensors and present high binding specicity for their respective antigens. 28 Among the various transduction techniques currently available, electrochemical impedance spectroscopy (EIS) has been widely applied in biosensor development in order to evaluate the interfacial properties of the modied electrodes.…”
