In recent years, nanostructured materials have emerged as potential candidates offering excellent prospects for interfacing the detection of biomolecules. Nanomaterials such as nanoparticles, nanostructured silicates, nano-sized metal oxides, nanostructured polymers, quantum dots, nanocomposites and sensing nanodevices are being utilized worldwide for fabrication of chemical sensors and sensor arrays with tailored characteristics and tuneable properties. Among above, the materials that create a matrix structure at the nanoscale level are particularly fascinating. The exceptional physical, chemical, mechanical and electrical properties of these matrices advocate their application in the electrode modification resulting in sensing devices and transducers with superior performance. Here we present an overview of different types of nanostructured networks that are applied in sensor development. The role of these materials in chemical sensors is described along with the techniques that are the backbone of the sensing process. Special attention has been given to some key sensors that are directly related to human physiology and have clinical significance.

Promotion of the conversion of CO 2 into HCO 3 − is necessary for the efficient sequestration of CO 2 into metal carbonate minerals, a promising CO 2 utilization strategy. Carbonic anhydrase (CA), a ubiquitous enzyme, exhibits high activity in CO 2 hydration and suffers from inherent instability as a biological disadvantage. Consequently, there is a demand for a CA-mimetic catalyst that is stable at high temperatures and can be easily prepared. In this study, we have developed a new CA-mimetic nanotube (CMNT) catalyst, demonstrating remarkable catalytic activity in CO 2 hydration. The CMNT catalyst is easily prepared by the layer-by-layer (LbL) method, which involves the sequential infusion of polyelectrolyte and polypeptide solutions into a track-etched polymeric membrane. Multiple catalytic Zn-histidyl imidazole complexes were built on the inner channel of nanotubes, on which CO 2 hydration takes place. CMNT follows Michaelis−Menten kinetics with a catalytic activity (k cat /K M ) of 8.2 M −1 s −1 at pH 7.5, comparable to those of other CA-mimetic catalysts. Remarkably, CMNT maintains its catalytic activity at 70 °C, a temperature that destabilizes CA. Sequestration of CO 2 into calcites was demonstrated with extensive characterization of CMNT and catalytic activity. Moreover, the CMNT-integrated membranes could be applied to continuous CO 2 hydration. This work underlines the straightforward preparation of a CA-mimetic catalyst using an established technique, offering the potential for future modification or incorporation of additional catalytic functions.
