“…It is known, that ZnO has high value of isoelectric point (pH~9.1) [34,35,43,62,[66][67][68][69][74][75][76][77] which makes ZnO nanostructures attractive for immobilization of biomolecules on its surface. It is important to note that the morphology and the structure properties of ZnO play important role in the process of immobilization.…”

“…Although the nanostructured interfaces designed by ALD for biofuel cells applications have not been reported yet, work in progress in our groups show that the TiO 2 deposited by ALD can efficiently immobilize enzymes that allow potential applications in biofuel cells. Recently we reported the tuning of optical and electrical properties of ZnO thin film deposited by ALD using different approaches: (i) control of the ZnO thickness [15], (ii) deposited of Al 2 O 3 /ZnO nanolaminates [14], (iii) using electrospun nanofibers as a template [5,54,55], and (iv) using ZnO as an active medium in a fiber-optic Fabry-Perot interferometer [56]. The improved optical and electrical properties of ZnO deposited by ALD makes them prominent materials for optical and electrical biosensors applications.…”

The most fundamental phenomena in the immobilising of biomolecules on the nanostructured materials for energy, environmental and health applications are the control of interfaces between the nanostructures/nanopores and the immobilized biomaterials. Thus, the throughput of all those biobased nanostructured materials and devices can be improved or controlled by the enhanced geometric area of the nanostructured interfaces if an efficient immobilization of the biomolecules is warranted. In this respect, an accurate control of the geometry (size, porosity, etc.) and interfaces is primordial to finding the delicate balance between large/control interface areas and good immobilization conditions. Here, we will show how the atomic layer deposition (ALD) can be used as a tool for the creation of controlled nanostructured interfaces in which the geometry can be tuned accurately and the dependence of the physical-chemical properties on the geometric parameters can be studied systematically in order to immobilize biomolecules. We will show mainly examples of how these methods can be used to create single nanopores for mass spectroscopy and DNA sequencing, and membrane for gas separation and water treatment in which the performance varies with the nanostructure morphologies/interfaces and the immobilization conditions.

Electrospun one-dimensional (1D) nanostructures are rapidly emerging as key enabling components in gas sensing due to their unique electrical, optical, magnetic, thermal, mechanical and chemical properties. 1D nanostructures have found applications in numerous areas, including healthcare, energy storage, biotechnology, environmental monitoring, and defence/security. Their enhanced specific surface area, superior mechanical properties, nanoporosity and improved surface characteristics (in particular, uniformity and stability) have made them important active materials for gas sensing applications. Such highly sensitive and selective elements can be embedded in sensor nodes for internet-of-things applications or in mobile systems for continuous monitoring of air pollutants and greenhouse gases as well as for monitoring the well-being and health in everyday life. Herein, we review recent developments of gas sensors based on electrospun 1D nanostructures in different sensing platforms, including optical, conductometric and acoustic resonators. After explaining the principle of electrospinning, we classify sensors based on the type of materials used as an active sensing layer, including polymers, metal oxide semiconductors, graphene, and their composites or their functionalized forms. The material properties of these electrospun fibers and their sensing performance toward different analytes are explained in detail and correlated to the benefits and limitations for every approach.
