Problem Description & Market Need(What is the problem? Or, What is needed in the market? And, How big is the potential market? What is the disease (if it’s a medical talk)? )

  • Variety of sensors provide increased efficiency and ecological safety in many industries. Their use is important factor for improvement of the life quality for modern society.
  • Application of traditional methods for monitoring of hazardous substances in variable environment (air, water, waste, etc.)is not often effective and has a range of drawbacks, mainly complicity and long-term exposure.
  • The main problem in developing of sensor systems is to supply them with the exceptional selectivity towards a different analytes to be detected in environment.

Brief technology description

CALIXARENE BASED CHEMOSENSOR GAZ-1

Main technical characteristics

  • Array of quartz crystal resonators covered with calixarenecontaining receptors which have different sensitivity towards different volatile organic molecules were developed.
  • Due to adsorption of analyte molecules onto sensitive surfaces of sensors frequency of quartz resonators is reducing. This frequency shift is considered as a sensor response.
  • Obtained array of sensors responses to pulse of analyte vapor is used for “teaching” system and after that – for recognition of chemical image of analyte by means of special mathematical apparatus for statistical treatment (PCA, Neural Network, etc.).

Working cell volume 9 sm3

Number of channel 8; Frequency drift less 0.5 Hz/ 1h

Counter range 0 –16 MHz;

Resolution 1 Hz;

Time single freq. count. 1s;

Time of measuring for recognition less 5 min;

Number of recognizing chem. images more 10;

Range of analyte concentration 10 – 10000 ppm;

Working temperature 20 – 30

Software DOS, Win9X;

Power supply 12V/0.4A

advantages what is my unique and overwhelming technology advantage

Experimental results
  • Kinetic response strongly depends on interaction between sensitive layer and analyte molecules. Thus, choosing array for given purpose we consider physical-chemical features of sensitive layers.
  • Response of several sensors to various analytes
stage of development clinical tests if medical and international patents
Stage of development (clinical tests if medical) and international patents
  • The series of calixarene based receptors of ions and neutral molecules were synthesized in the Institute of Organic Chemistry NASU (see www.ioch.kiev.ua/calix )
  • The sensitive calixarene based polymer films were prepared in the Institute of Macromolecular Chemistry NASU
  • The several chemosensor devices were constructed in the Institute of Semiconductor Physics NASU.

STCU project #3643 “Development of chemosensor materials and equipment for detection toxic substances and pollutants in the environment”
