Project summary

One of the most important branches of modern nanoscience and nanotechnology is the so-called sensor technology combining the latest achievements in highly sensitive intelligent materials first of all multifunctional chemochips with immobilized sensing fragments with nanoscale function [1-4] and different microdevice construction with high processing speed and reliability.

Of especial interest are the materials close to natural objects in their properties and functions, such as high sensitivity and adaptability [5]. In this context, great attention is being given to the self-assembling systems capable of hierarchical ordering from the nano- to mesoscopic level [6], which may lead to elaboration of intelligent in particular, optically sensing, materials responsive to weak external influences ever claimed at the world market of intellectual property.

This Project aims at fabrication and study of intelligent multifunctional nano-sized sensing materials for use in devices for monitoring pollutants of environment, viz. the inorganic structure/biopolymer/organic chromophore hybrods sensitive to chemical factors – presence of heavy metal ions in liquid media, and capable of self-adjusting to changing radiation conditions and accumulation o radiation damages.

Tasks to be solved during Project implementation:


1. Preparation and characterization of inorganic composites based on nano-sized carbon.
2. Synthesis and characterization of photochromic compounds sensitive to the presence of heavy metals in liquids.
3. Synthesis and characterization of compounds exhibiting optical response to -radiation.
4. Immobilization of sensing units in inorganic composite matrices based on nano-diamond.
5. Radiation tests and radiation photonics of sensing units, designed for monitoring liquid media.

A specific feature of the approach proposed to research basis elaboration necessary for creation of universal multifunctional sensing units with response to outer stimuli is the use of absorption/luminescent visualization method including conditions of heavy irradiation. We are planning to synthesize a variety of sensing materials each of those containing an oligomeric or low-molecular luminescent selective indicator immobilized in a carbon-based common inorganic substrate.

Thanks to a low cost of sensing elements and hybrid materials, the results can be expected to have good perspectives on the market of nanosystem technique. The Project corresponds to all requirements to the modern nanoscience, its conjuncture, and market demands.
