AP08856173 — Synthesis and study of the properties of low-dimensional semiconductor materials for the creation of highly sensitive biosensors

Objective of the project: To develop low-cost methods for the controlled synthesis of low-dimensional semiconductor materials, to study their physical and chemical properties in order to create highly sensitive bioanalytical devices for use in medicine, sensor electronics, for monitoring the state of the environment, and quality control of food industry products.

Relevance: The development of biosensors capable of rapid detection of target analytes reaching nano/picomolar concentrations of biomolecules based on semiconductor nanomaterials is an important direction for public health in assessing physiological and metabolic parameters, as well as environmental protection. The luminescent, photocatalytic, piezoelectric, chemical, and semiconductor properties of ZnO and composites based on it make it possible to create biosensors using various types of signal detection. The scientific novelty of the project lies in the development of low-cost methods for the synthesis of composites of semiconductor and carbon nanomaterials, the study of their physical and chemical properties, the substantiation of the dependence of properties on the geometric parameters and structure of the synthesized composite compounds, the combination of the unique properties of which will make it possible to obtain new materials that are promising for use in the creation of analytical devices with high sensitivity and selectivity.

Scientific adviser:  Ph.D., Associate Professor, Gritsenko Lesya Vladimirovna

Results obtained: Within the research project, a simple and environmentally friendly chemical precipitation method for synthesizing ZnO nanoparticles was developed, enabling the production of highly crystalline structures with controlled morphology. The influence of alkali concentration on the structural, optical, and photocatalytic properties of ZnO was established, and optimal conditions for efficient degradation of organic pollutants were identified. A low-cost method for synthesizing ZnO–CuO composite structures was developed, and the effect of composition on photocatalytic activity was investigated. Highly oriented ZnO nanostructures on ITO substrates were fabricated, demonstrating high efficiency in enzyme immobilization and biosensor development. The modified electrodes showed high sensitivity in glucose detection. A fiber-optic biosensor for detecting the CD44 biomarker was developed, exhibiting high selectivity and reproducibility. The obtained results highlight the potential of these materials for applications in photocatalysis, sensor electronics, and medical diagnostics.
