Molecularly imprinted polymers (MIPs) are currently widely used and further developed for biological applications. The MIP synthesis procedure is a key process, and a wide variety of protocols exist. The templates that are used for imprinting vary from the smallest glycosylated glycan structures or even amino acids to whole proteins or bacteria. The low cost, quick preparation, stability and reproducibility have been highlighted as advantages of MIPs. The biological applications utilizing MIPs discussed here include enzyme-linked assays, sensors, in vivo applications, drug delivery, cancer diagnostics and more. Indeed, there are numerous examples of how MIPs can be used as recognition elements similar to natural antibodies.

β-blockers are a significant class of medications generally used to treat cardiovascular related diseases, but toxicity from overdoses can lead to serious side effects. In addition to this, they may also be used as doping agents by athletes due to their sedative effects. Therefore, it is crucial for their detection. Traditional detection methods include chromatography, spectroscopy, etc., but these techniques are tedious and labor-intensive, and the instruments are cumbersome. Electrochemical methods have become an important alternative to traditional methods because of their high selectivity, high sensitivity, minimal expense, and portability. For the purpose of enhancing the performance of electrochemical methods, this article focuses on three types of electrode modification materials: molecularly imprinted polymers (MIPs), carbon nanomaterials, and metal nanoparticles. MIPs are an important class of selective adsorption materials, which can adsorb a certain type of β-blockers through hydrophobic interaction, π-π interaction, hydrogen bonding, etc., thereby improving the selectivity and sensitivity of electrochemical sensors. Carbon nanomaterials and metal nanoparticles have strong electroconductivity and enormous specific surface area, which can promote the electron transfer rate on the working electrode surface and improve the sensitivity of the sensor. In addition, they also have some unique properties respectively. Furthermore, the trend of electrochemical detection of β-blockers and the prospect of future development are suggested.

Quality control of medicines is of extreme importance since its use is carried out on a large scale throughout the world, and any errors in its production directly affect the effectiveness of the same, as well as the people who use them. Therefore, the search for more sensitive, selective, lower cost and easy handling methods is essential for this control to be done efficiently. Among the techniques that present such characteristics, electroanalytical techniques stand out, especially with the use of modified sensors, both for determination and for quantification of drugs. One of the modifiers that see gaining space in this area are molecularly printed polymers (MIPs), which appear as a promising tool for the development of systems with biomimetic recognition, similar to specific systems (antigen-antibody). The advantages of MIPs relative to biological materials include easy and low cost preparation and simple storage, which often occurs at room temperature for long periods of time. Despite the diversity of work involving MIPs in the preparation of samples in general, their application as modifying agents in sensors for any analyte is still restricted. Thus, the present review aims to evaluate the application of modified MIP sensors for the determination of drugs in biological and pharmaceutical samples and the progress of this analytical methodology in the present time.
