Nanostructures: design, preparation, applications
Keywords: materials, characterization, nanostructures, laser ablation, devices
Background and Motivation
The special structure of nanomaterials gives rise to their amazing properties, frommagnetic to mechanical, from electric to optical, among others. As such, nanostructures arevery attractive candidates for photocatalysis, sensing and photonic devices, as they have acombination of unique electronic and optical properties. Importantly, the shape and size ofnano-objects define their physical properties, and hence the ability to manipulate themorphology and composition at the nanoscale provides immense opportunities for creating
new materials with superior performance for new products and devices. Therefore, thepresent research aims at three main goals: (i) preparation of novel nanomaterials withvarious morphologies and chemistries (via laser ablation in liquid and wet-chemistry
approaches); (ii) study of their formation and properties; (iii) design and fabrication ofdevices (such as, e.g., chemiresistive gas and photonic sensors) or using the preparednanostructures as materials for applications in photovoltaics, photocatalysis and so on; and(iv) development of biomedical materials that use laser-generated nanomaterials.

The originality and innovative nature of theproject are based on: (i) exploiting the ability oflaser beam to produce nanomaterials with uniqueproperties; (ii) systematic approach to productionof nanostructures with different morphologies andchemistries and testing them in sensing andphotonic devices; (iii) combining surface-science,chemical and optical analyses (multidisciplinaryapproach) to nanostructures as potential building
blocks for devices; (iv) developing devices that
employ chemical, optical and even medicinal
properties of nanostructures.

Impact and Perspective
The growing industrial demand for cost-efficient, flexible and reliable technologies for the fabrication ofcomponents and devices at small physical scales requires new breakthrough approaches to the preparation,
morphology control, and processing of nanomaterials. The current project deals with new approaches to growdiverse novel nanomaterials with various morphologies, sizes and chemistries, their characterization and surface
modification, with the final goal to fabricate nanomaterial-based devices, such as, e.g., chemiresistive orphotonic sensors that use nanostructures to detect gases, saturable absorbers for lasers, photovoltaic cells, or to
use them as photocatalysts, nanocontainers in biomedical materials, and so on.
