2 2 Talk outline 1.What is needed in the market? 2.Brief technology description. 3.Stage of development. 4.Who needs it & how many will they need? 5.What is my unique technology advantage? 6.Competitive matrix. 7.How will I beat the competition? 8.Opportunity for joint work.

3 3 Proprietary information statement The technology material presented in this talk is available for licensing or joint product development. None of the slides contain any confidential or proprietary information which would prevent patenting the technology.

4 4 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 its 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.

5 5 Brief technology description 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 – ppm; Working temperature 20 – 30 Software DOS, Win9X; Power supply 12V/0.4A CALIXARENE BASED CHEMOSENSOR GAZ-1 Main technical characteristics

6 6 Advantages (What is my unique and overwhelming technology advantage?) Calixarene based Electronic Nose is used for: monitoring of hazardous pollutants in environment; quality control in food industry and agriculture; quality control of perfumes and beverages.

7 7 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 TolueneBenzenen-xyleneChloroformDichlorethaneCH 2 Cl 2 CCl Response (freuency shift, Hz) Analyte Coating type CA2 CA6 CA7 CA10 CA11 CA12 CA13 CA14

8 8 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

9 9 Targeted Market Segment (Who needs it? How many will they need? What price are they willing to pay, what do they pay now?) Food industry and agriculture Chemical industry Quality control of of perfumes and beverages

10 10 Competition (Who is my competition? How will I beat the competition?)

11 11 Competitive Matrix Important product or technology characteristics My company or institutes product Name of Competitor #1 Name of Competitor #2, etc. Key Characteristic (a) Key Characteristic (b) Key Characteristic (c) Key Characteristic (d) (usually cost)

12 12 Opportunities (What I am seeking. Opportunity for joint work. Seeking potential partners and licensees. And, How much will it cost?) We offer the Electronic Nose for: Food industry and agriculture Chemical industry Quality control of perfumes and beverages
