“…Usually, IF is called an imprinting factor, whereas Ayerdurai et al [ 47 ] argued that an apparent imprinting factor is a more correct term for IF. According to the measurements, the MIP-Ppy/SPCE had an apparent imprinting factor toward the Listeria monocytogenes bacteria that was approximately four times higher than that registered by the NIP-Ppy/SPCE electrode.…”

Detecting bacteria—Listeria monocytogenes—is an essential healthcare and food industry issue. The objective of the current study was to apply platinum (Pt) and screen-printed carbon (SPCE) electrodes modified by molecularly imprinted polymer (MIP) in the design of an electrochemical sensor for the detection of Listeria monocytogenes. A sequence of potential pulses was used to perform the electrochemical deposition of the non-imprinted polypyrrole (NIP-Ppy) layer and Listeria monocytogenes-imprinted polypyrrole (MIP-Ppy) layer over SPCE and Pt electrodes. The bacteria were removed by incubating Ppy-modified electrodes in different extraction solutions (sulphuric acid, acetic acid, L-lysine, and trypsin) to determine the most efficient solution for extraction and to obtain a more sensitive and repeatable design of the sensor. The performance of MIP-Ppy- and NIP-Ppy-modified electrodes was evaluated by pulsed amperometric detection (PAD). According to the results of this research, it can be assumed that the most effective MIP-Ppy/SPCE sensor can be designed by removing bacteria with the proteolytic enzyme trypsin. The LOD and LOQ of the MIP-Ppy/SPCE were 70 CFU/mL and 210 CFU/mL, respectively, with a linear range from 300 to 6700 CFU/mL.

The fields of biosensing have been transformed by the discovery of extraordinary molecular recognition components, such as aptamers and biomimetic receptors. Systematic Evolution of Ligands by Exponential Enrichment (SELEX) is a method used to select aptamers, or short sequences of single-stranded DNA (ssDNA) or RNA (ssRNA), based on their unique binding affinity to target molecules. Molecularly imprinted polymers (MIPs) are a type of biomimetic receptor that mimics the selectivity of natural receptors inside a synthetic matrix. They make it possible to identify pathogens, and illness biomarkers with accuracy. Aptamers and biomimetic receptors play crucial roles in various fields including diagnostics, therapeutics, and biosensing. Their high specificity, versatility, and adaptability enable targeted detection, drug delivery, and biomolecule manipulation, thereby contributing to advancements in personalized medicine, biotechnology, and disease diagnosis. Aptamers and biomimetic receptors have been combined with cutting-edge technologies, like nanotechnology and lab-on-a-chip systems, to create biosensors that are quick, portable, and extremely sensitive. These recognition features are anticipated to become more important as technology develops, helping to address global issues, advance biosensing capabilities, and raise people's standard of living everywhere. Recent advancements and innovation on Aptamers and Biomimetic Receptors in Biosensing have been discussed in this review article.
