“…Cell culture still remains a standard technique for identifying bacterial species; however, it usually requires 24-48 hours, depending on the growth speed of the target bacterium [101]. These methods generally require a high level of technical skill, and complex sample preparation.There is therefore an industry-driven requirement to design novel, rapid and reliable analytical detection methods for microorganisms.A QCM sensor platform was developed for the detection of Escherichia coli, Bacillus Cereus, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus[101][102][103]. Imprinted PPy and PU were generated directly on sensor surface.…”

Since their conception fifty years ago, molecularly imprinted polymers (MIPs) have seen extensive development both in terms of synthetic routes and applications. Perhaps the most challenging target for molecular imprinting are cells. Though early work was based almost entirely around microprinting methods, recent developments shifted towards epitope imprinting to generate MIP nanoparticles. Simultaneously, the development of techniques such as solid phase MIP synthesis have solved many historic issues of MIP production. This review briefly describes various approached used in cell imprinting with a focus on applications of the created materials in imaging, drug delivery, diagnostics and tissue engineering.

“…Nowadays, the most frequently used strategies for surface imprinting of bacteria is the microcontact stamping method in a prepolymerized crosslinking polymeric network such as polyurethanes, polymethylsiloxanes (PDMS) or polyacrylates [33b,c, 66–68] . Typically, the bacteria suspension is drop‐casted on a glass slide and allowed to dry so that randomly attached cells are left on the glass slide (Figure 4).…”

Fighting Antibiotic‐Resistant Bacteria: Promising Strategies Orchestrated by Molecularly Imprinted Polymers

Infections caused by antibiotic‐resistant bacteria are difficult and sometimes impossible to treat, making them one of the major public health problems of our time. We highlight how one unique material, molecularly imprinted polymers (MIPs), can orchestrate several strategies to fight this serious societal issue. MIPs are tailor‐made biomimetic supramolecular receptors that recognize and bind target molecules with high affinity and selectivity, comparable to those of antibodies. While research on MIPs for combatting cancer has flourished, comprehensive work on their involvement in combatting resistant superbugs has been rather scarce. This review aims at filling this gap. We will describe the causes of bacterial resistance and at which level MIPs can deploy their weapons. MIPs’ targets can be biofilm constituents, quorum sensing messengers, bacterial surface proteins and antibiotic‐deactivating enzymes, among others. We will conclude with the current challenges and future developments in this field.

“…The detection limit was 1.6 × 10 8 cells/mL and this sensor also showed a high selectivity towards the imprinted template (E. coli B strain) and a very close bacterial strain (E. coli W strain). Spieker and co-authors implemented this technique into a QCM sensor for the detection of Bacillus cereus [49]. In this study, the affinity of five different polymers (polystyrene, polyacrylate, polyvinylpyrrolidone, polyacrylamide and polyurethane) towards B. cereus was screened at first.…”

Foodborne diseases caused by bacterial pathogens pose a widespread and growing threat to public health in the world. Rapid detection of pathogenic bacteria is of great importance to prevent foodborne diseases and ensure food safety. However, traditional detection methods are time-consuming, labour intensive and expensive. In recent years, many attempts have been made to develop alternative methods for bacterial detection. Biosensors integrated with molecular imprinted polymers (MIPs) and various transducer platforms are among the most promising candidates for the detection of pathogenic bacteria in a highly sensitive, selective and ultra-rapid manner. In this review, we summarize the most recent advances in molecular imprinting for bacterial detection, introduce the underlying recognition mechanisms and highlight the applications of MIP-based biosensors. In addition, the challenges and future perspectives are discussed with the aim of accelerating the development of MIP-based biosensors and extending their applications.
