“…A prepared bacteria-imprinted conductive poly (3-thiopheneacetic acid) film was deposited on gold electrodes. The structure and performance of the biosensor was characterized by microscopy and electrical measurements, and the results suggested an LOD of 2 CFU/mL within a response time of 10 min [23] . The sensitivity of this design was the highest compared to previously reported S. aureus biosensors.…”

“…As a result, the stable and reusable properties have increased the long shelf-life usability of MIPs. Some studies reported the shelf life of MIPs is a minimum of 6 weeks [132] and a maximum of 6 [133] to 12 months [134] for MIP-based biosensors stored at 25 • C. This method is considered a versatile and hopeful technique that can recognize both biological and chemical analytes, including nucleotides [135], amino acids [136], enzymes [137], proteins [138], phosphoproteins [139], viruses [140], bacteria [141], pollutants [142], dyes [143], food poisons [144], pesticides [145], and toxins [146,147].…”

The molecular imprinting technique is a quickly developing field of interest regarding the synthesis of artificial recognition elements that enable the specific determination of target molecule/analyte from a matrix. Recently, these smart materials can be successfully applied to biomolecule detection in biomimetic biosensors. These biosensors contain a biorecognition element (a bioreceptor) and a transducer, like their biosensor analogs. Here, the basic difference is that molecular imprinting-based biosensors use a synthetic recognition element. Molecular imprinting polymers used as the artificial recognition elements in biosensor platforms are complementary in shape, size, specific binding sites, and functionality to their template analytes. Recent progress in biomolecular recognition has supplied extra diagnostic and treatment methods for various diseases. Cost-effective, more robust, and high-throughput assays are needed for monitoring biomarkers in clinical settings. Quartz crystal microbalance (QCM) biosensors are promising tools for the real-time and quick detection of biomolecules in the past two decades A quick, simple-to-use, and cheap biomarkers detection technology based on biosensors has been developed. This critical review presents current applications in molecular imprinting-based quartz crystal microbalance biosensors for the quantification of biomarkers for disease monitoring and diagnostic results.

Safety and quality are key issues for the food industry. Consequently, there is growing demand to preserve the food chain and products against substances toxic, harmful to human health, such as contaminants, allergens, toxins, or pathogens. For this reason, it is mandatory to develop highly sensitive, reliable, rapid, and cost-effective sensing systems/devices, such as electrochemical sensors/biosensors. Generally, conventional techniques are limited by long analyses, expensive and complex procedures, and skilled personnel. Therefore, developing performant electrochemical biosensors can significantly support the screening of food chains and products. Here, we report some of the recent developments in this area and analyze the contributions produced by electrochemical biosensors in food screening and their challenges.
