“…These unique imprinted materials are capable of microorganism trapping by combined size-shape discrimination and affinity recognition. Perez et al [ 26 ] demonstrated selective binding of rod-shaped (Listeria monocytogenes ) and coccoidal ( Staphylococcus aureus ) bacteria from a mixture of both on beads imprinted with one or the other. Harvey et al [ 27 ] used affinity augmented beads imprinted with Bacillus thuringiensis and Bacillus anthracis as a semi-selective matrix to capture and concentrate their specific spores based on same principles.…”

Thin films of organically modified silica (ORMOSILS) produced by a sol-gel method were imprinted with whole cells of a variety of microorganisms in order to develop an easy and specific probe to concentrate and specifically identify these microorganisms in liquids (e.g., water). Microorganisms with various morphology and outer surface components were imprinted into thin sol-gel films. Adsorption of target microorganism onto imprinted films was facilitated by these macromolecular fingerprints as revealed by various microscopical examinations (SEM, AFM, HSEM and CLSM). The imprinted films showed high selectivity toward each of test microorganisms with high adsorption affinity making them excellent candidates for rapid detection of microorganisms from liquids.

“…673 Cross-linking of poly(allylamine) with diacylchlorides in an interfacial polycondensation at the surface of an aqueousdispersed organic droplet had earlier been used as the first step in the imprinting of bacteria. 674,675 Subsequent polymerization of the organic core resulted in macroscopic surface imprints of the organisms Staphylococcus aureus and Listeria monocytogenes on polymer beads. Similar planar format imprints in a modified polyurethane were also demonstrated.…”

Over 1450 references to original papers, reviews and monographs have herein been collected to document the development of molecular imprinting science and technology from the serendipitous discovery of Polyakov in 1931 to recent attempts to implement and understand the principles underlying the technique and its use in a range of application areas. In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by papers dealing with fundamental aspects of molecular imprinting and the development of novel polymer formats. Thereafter, literature describing attempts to apply these polymeric materials to a range of application areas is presented.

“…Due to their exceptional characteristics, MIPs are considered as potential candidate for virus sensing applications and often exhibit high recognition proficiency and selectivity [62]. There are a variety of imprinting strategies for microorganisms' detection [63]; however, in the following sub-sections, we shall focus on the selected approaches that have been typically employed in QCM based viral diagnostics. Table 1 shows the selected examples of virus-MIP based QCM biosensors and their detection limits.…”

Viruses are pathogenic microorganisms that can inhabit and replicate in human bodies causing a number of widespread infectious diseases such as influenza, gastroenteritis, hepatitis, meningitis, pneumonia, acquired immune deficiency syndrome (AIDS) etc. A majority of these viral diseases are contagious and can spread from infected to healthy human beings. The most important step in the treatment of these contagious diseases and to prevent their unwanted spread is to timely detect the disease-causing viruses. Gravimetric viral diagnostics based on quartz crystal microbalance (QCM) transducers and natural or synthetic receptors are miniaturized sensing platforms that can selectively recognize and quantify harmful virus species. Herein, a review of the label-free QCM virus sensors for clinical diagnostics and point of care (POC) applications is presented with major emphasis on the nature and performance of different receptors ranging from the natural or synthetic antibodies to selective macromolecular materials such as DNA and aptamers. A performance comparison of different receptors is provided and their limitations are discussed.
