“…Such gas aggregation sources of nanoparticles (GAS), introduced in the early‐1990s of the last century by Haberland et al, posseses in comparison with techniques based on chemical synthesis advantageous features such as relative simple and effective production of NPs, no or only limited use of potentially harmful solvents or chemical precursors as well as the possibility to combine the gas aggregation sources of nanoparticles with other vacuum‐based deposition methods. The latter enabled production of complex functional nanocomposite or nanostructured materials with different architectures including classical nanocomposites or multi‐layered structures, coatings with dual‐scale roughness, or materials with horizontal gradients of NPs embedded into a matrix material . Furthermore, the GAS systems were proved to be highly flexible also in terms of composition of produced NPs as they enabled fabrication of metallic, metal‐oxide as well as polymeric NPs …”

Core@shell Cu/hydrocarbon plasma polymer nanoparticles (NPs) have been prepared using a gas aggregation cluster source followed by in‐flight plasma polymer coating of produced Cu NPs. Conventional plasma polymerization of vapors of n‐Hexane or acetone has been applied. It is shown that this strategy for core@shell NPs production enables to achieve homogeneous shells with thickness in nanometer scale without impact on the properties of metallic cores (crystallinity, optical properties). In addition, it has been proved that the chemical properties of shells may be controlled by use of different organic precursors that enables production of NPs with different wettabilities.

Over the past few decades the fabrication of nanoscale materials for use in chemical sensing, biomedical and biological analyses has proven a promising avenue. Nanomaterials show promise in such chemical and biological analysis mainly due to their highly tunable size- and shape-dependent chemical and physical properties. Furthermore, they exhibit unique surface chemistry, thermal stability, high surface area and large pore volume per unit mass that can be exploited for sensor fabrication. This review will discuss the chemical and physical properties of nanomaterials necessary for use as chemosensors and biosensors. It will also highlight some noteworthy recent avenues using nanoscale materials as scaffolds for chemosensing and biosensing. Nanomaterials that have proven to be useful for the fabrication of sensors, as reviewed herein, have compositions including metals, metal oxides, chalcogenides and polymers. Their structures range from nanoparticles, nanorods, and nanowires to nanoporous and core-shells. Examples of the different types of structures and compositions as well as sensors and biosensors fabricated from them will be described. Some nanomaterials are functionalized with various kinds of ligands and bioactive groups to produce sensitive and selective sensors for specific analytes. The combination of two or more types of nanostructures with core-shell type nanoassemblies and other composite structures, in addition to advantageous features enhancing sensitivity and response time of related sensors, are also discussed.
