Description:

Today, food safety is a growing concern for food production and supply industries. Currently, the conventional techniques being used in the food industries for foodborne pathogen detection are culture and colony counting, Enzyme-linked Immunosorbent Assay (ELISA), and Polymerase Chain reaction (PCR). These techniques are not feasible for continuous monitoring since they are time consuming and require expensive equipment and highly trained personnel. Biosensors have been the latest development in real-time detection of food pathogens since they can provide rapid and continuous, simple, reliable diagnostic of foodborne colonization and contamination in food production settings. This project aims to design an electrochemical biosensor platform for the detection of Salmonella by using electro-deposition of Platinum nanostructures in combination with temperature-responsive polymer nanobrushes and aptamers specific to Salmonella as the biorecognition element. In order to carry out the deposition of nanoplatinum structure onto the electrode surface Pulsed Sonochemical Electrodeposition (pulSED) technique are used. For analyzing the effectiveness of the developed biosensor platform, the Electroactive Surface Area (ESA) values from Cyclic Voltammetry (CV) are observed and actuation tests are performed in order to check polymer’s response to different temperatures in purified media and complex food systems. Results are compared with conventional methods and published biosensors. |
