“…Owing to the delicate nature of microorganisms, soft-lithography is an appropriate stamping technique for patterning polymeric materials, thus generating selective biomimetic surfaces [71,72]. It is a surface imprinting technique that has been extensively applied for macromolecular imprinting in the last two decades [73,74].…”

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.

“…Therefore, carbohydrate diol groups have diverse reactivity toward boronic acid with the following trend: 1,2 cis diol 4 1,3 diol c 1,2 trans diol. 67 Here, we will provide a few recent diagnostic approaches using molecular imprinting. To further improve glycan selectivity, boronic acid derivatives have been synthesized and tested.…”

Diagnosis is an essential launching point for accurate medical treatment, and rapid and accurate diagnostic approaches have become the increasingly vital goal inspiring developments in a variety of analytical methods. With increasing attention in the area of glycosciences, the roles that carbohydrates play in many diseases have been elucidated, and the use of carbohydrates as disease biomarkers has become an emerging diagnostics strategy. This review article does not intend to comprehensively include all carbohydrate-related diagnostics studies. We do, however, wish to describe carbohydrate recognition and the design of sensitive detecting devices, especially those developed recently, so that readers might better grasp the principles behind such devices and relevant detection strategies, particularly those favoring inexpensive, rapid, and point-of-care (POC) approaches.

“…The typical imprinting stamp is produced by self-assembly of the template biomolecules on top of a smooth support under appropriate conditions and the self-assembled template stamp is then softly pressed over a prepolymer film for a certain period of time (Mujahid et al, 2013). The template biomolecules should be strictly packed in order to attain high imprinting density (Dickert et al, 2004;Mujahid et al, 2013). Overall, this procedure allows the production of geometrical features of a wide range of biomolecules and translates the chemical information involved in noncovalent interactions between the polymeric functional groups and the receptor surface (Mujahid et al, 2013).…”
