“…In general, silica is one of the most commonly used precursors for inorganic hybrids. However, other inorganic components such as inorganic oxides, minerals, clays, noble metal nanoparticles and carbon-based materials may also act as precursors for inorganic-inorganic enzyme supports [199][200][201][202]. An interesting example of an inorganic-inorganic composite used for enzyme immobilization is a combination of calcium carbonate and gold nanoparticles (CaCO 3 -AuNPs).…”

In recent years, enzyme immobilization has been presented as a powerful tool for the improvement of enzyme properties such as stability and reusability. However, the type of support material used plays a crucial role in the immobilization process due to the strong effect of these materials on the properties of the produced catalytic system. A large variety of inorganic and organic as well as hybrid and composite materials may be used as stable and efficient supports for biocatalysts. This review provides a general overview of the characteristics and properties of the materials applied for enzyme immobilization. For the purposes of this literature study, support materials are divided into two main groups, called Classic and New materials. The review will be useful in selection of appropriate support materials with tailored properties for the production of highly effective biocatalytic systems for use in various processes.

“…A sol-gel sensor technology was applied to manufacture an enzymatic biosensor based on the immobilization of pkDAAO by sol-gel on a glass covered carbon electrode surface modified by electrodeposition of gold nanofilm (Au-NF) and MWCNTs [ 68 ]. The linear relationship between biosensor response and D-Ala concentration was excellent (ranging from 0.25 to 4.5 μM).…”

D-enantiomers of amino acids (D-AAs) are only present in low amounts in nature, frequently at trace levels, and for this reason, their biological function was undervalued for a long time. In the past 25 years, the improvements in analytical methods, such as gas chromatography, HPLC, and capillary electrophoresis, allowed to detect D-AAs in foodstuffs and biological samples and to attribute them specific biological functions in mammals. These methods are time-consuming, expensive, and not suitable for online application; however, life science investigations and industrial applications require rapid and selective determination of D-AAs, as only biosensors can offer. In the present review, we provide a status update concerning biosensors for detecting and quantifying D-AAs and their applications for safety and quality of foods, human health, and neurological research. The review reports the main challenges in the field, such as selectivity, in order to distinguish the different D-AAs present in a solution, the simultaneous assay of both L- and D-AAs, the production of implantable devices, and surface-scanning biosensors. These innovative tools will push future research aimed at investigating the neurological role of D-AAs, a vibrant field that is growing at an accelerating pace.

“…More interestingly, such materials can reversibly translate between liquid and solid under different stimuli conditions, which could not only be facilely utilized to detect external chemical and physical stimulations but also possess the self‐healing ability to mechanical work. Therefore, these adaptive systems have the potential to revolutionize technologies such as sensors and actuators, as well as numerous biomedical applications . For example, Kartha and co‐workers found that a fluorescent organogelator could exhibit capability for trinitrotoluene (TNT) in the gel form when compared to that in the solution state .…”

[38][39][40][41][42][43][44][45][46][47][48][49][50][51] For example, Kartha and co-workers found that a fluorescent organogelator could exhibit capability for trinitrotoluene (TNT) in the gel form when compared to that in the solution state. [45] They demonstrated that in n-hexane solution, the oligo (p-phenylenevinylene) perfluoroarene (OPVPF)-based gelator exhibits a green fluorescence which upon gelation turns to yellow, as shown in Figure 1B.…”

Sensors have attracted particular attention as analytical devices because of their importance in health and security. The ability to obtain unique functions using molecular design have rapidly advanced the use of organic optoelectronic materials of π‐conjugated compounds in electronic sensing devices. A brief introduction to sensors, focusing on organic micro‐ or nanoassemblies created using state‐of‐the‐art protocols for assembly and their recent development for high‐performance electronic sensing devices, is presented.
