“…In comparison, Clarindo et al synthesized MIPs for tetracycline, which was ground up and mixed with graphite-polyurethane composite electrode. The subsequent developed sensor demonstrated in the detection of tetracycline in different samples achieved a detection limit of 0.555 µM [50]. MIPs and aptamers have both also been demonstrated in fluorescence based optical sensors for the detection of tetracycline based antibiotics.…”

Effective molecular recognition remains a major challenge in the development of robust receptors for biosensing applications. Over the last three decades, aptamers and molecularly imprinted polymers (MIPs) have emerged as the receptors of choice for use in biosensors as viable alternatives to natural antibodies, due to their superior stability, comparable binding performance, and lower costs. Although both of these technologies have been developed in parallel, they both suffer from their own unique problems. In this review, we will compare and contrast both types of receptor, with a focus on the area of environmental monitoring. Firstly, we will discuss the strategies and challenges involved in their development. We will also discuss the challenges that are involved in interfacing them with the biosensors. We will then compare and contrast their performance with a focus on their use in the detection of environmental contaminants, namely, antibiotics, pesticides, heavy metals, and pathogens detection. Finally, we will discuss the future direction of these two technologies.

“…A more detailed and comprehensive review of MIP biosensors was reported by Gui et al [130]. A number of different approaches can be used to create MIPs, including the production of MIP particles for later integration into end use applications, such as sensors [131] and direct electropolymerisation onto the surface of a substrate [132].…”

Antimicrobial drug residues in food are strictly controlled and monitored by national laws in most territories. Tetracyclines are a major broad-spectrum antibiotic class, active against a wide range of Gram-positive and Gram-negative bacteria, and they are the leading choice for the treatment of many conditions in veterinary medicine in recent years. In dairy farms, milk from cows being treated with antibiotic drugs, such as tetracyclines, is considered unfit for human consumption. Contamination of the farm bulk tank with milk containing these residues presents a threat to confidence of supply and results in financial losses to farmers and dairy. Real-time monitoring of milk production for antimicrobial residues could reduce this risk and help to minimise the release of residues into the environment where they can cause reservoirs of antimicrobial resistance. In this article, we review the existing literature for the detection of tetracyclines in cow’s milk. Firstly, the complex nature of the milk matrix is described, and the test strategies in commercial use are outlined. Following this, emerging biosensors in the low-cost biosensors field are contrasted against each other, focusing upon electrochemical biosensors. Existing commercial tests that identify antimicrobial residues within milk are largely limited to beta-lactam detection, or non-specific detection of microbial inhibition, with tests specific to tetracycline residues less prevalent. Herein, we review a number of emerging electrochemical biosensor detection strategies for tetracyclines, which have the potential to close this gap and address the industry challenges associated with existing tests.

“…Essa montagem pode ser realizada por métodos tais como, preparação de filmes de sistemas sol-gel, eletropolimerização, gotejamento ou spin coating, e copolimerização de misturas contendo a molécula-molde e os monômeros. A modificação do corpo do eletrodo também já foi descrita, mas em uma quantidade menor de trabalhos (CERVINI e CAVALHEIRO, CLARINDO et al 2020;PEREIRA, CERVINI e CAVALHEIRO, 2014). Esse processo está ilustrado na Figura 1, usando o analito diclofenaco como molécula-molde.…”
