2 Outline Why Labeling Taiwan nanomark System APEC Collaboration on Nano Measurement International & Regional Activities on Nano Metrology

3 Number of Produc cts More & More Nanotech-enabled Products Entering the Market Product Categories Mar 8, 2006 Aug 21, Number of products from 21 countries : 212 (2006/03/08) 803 (2008/08/21) Paint is a sub-category under Home and Garden Display is a sub-category under Electronics and Computers Cross Cutting is a grouping of multi-functional products, e.g. coating Source:

4 Why Labeling With Nano, product price could be skyrocketed by more than ten times! Are They Real Nano-enabled Products?

5 Why Labeling Protect Consumers :Avoid waste money Protect Good Companies:Eliminate unfair competitions between good and bad products Increase Public Trust :Facilitate healthy development of nanotechnology Facilitate Trade :Stimulate economic growth

6 Advance Social Responsibility Approaches: Focus on Consumer Products

7 How to Choose which Products to Have nanomark? Impossible to certify all commercial nanoproducts Specification/Testing Methods are not all ready How to choose? Product Commercialized? Capable Testing Labs? Testing Methods? Prudent with Risk Potential Products, e.g. cosmetics Producers could suggest items provided enough information is ready

8 Requirements Basic Requirements Nano Scale (in principle, i < 100nm) Unique Properties Quality System Installed Safety Issues being taken care/traceable Products Contract to use nanomark

9 Example photocatalyst (UV & Visible light) Anti-bacterial Tiles How many bacteria have to be tested? Representative Safe/easy to handle How effective anti-bacterial tiles should be? achievable Staphylococcus aureus: ATCC 65389, BCRC Escherichia Coli:ATCC 8739, BCRC Testing Protocol (conditions, raw materials and/or final products) Top 50% Companies What should be specified on the product package? How to use where who how (application methods, maintenance, etc.) Reliability > 90%

10 Example photocatalyst (UV & Visible light) Anti-bacterial Tiles Tiles:N041 (900mm x 1800mm) (CERABO) N04590 (450mm x 900mm) (Ohayo) Who:Construction Companies, General Publics Where:Indoor (e.g.. toilet), Outdoor How: Adhesion to fix on the substrate Wet cloth to wipe if dirty Reliability:real case ( > 3 years) Wall Tile (45 x 90 cm) Floor Tile (90 x 90 cm) Test: Nano Scale:raw material, 40nm Product, confirmed to have TiO 2 Anti-bacteria:S. aureus 99.99% E. Coli 99.99% S. aureus 99.99% E. Coli 97.83% 365nm UV, 0.2mW/cm 2 /24 hrs 543nm, 1000 lx/24 hrs Quality System:ISO9001 (Certification:4XBY008-04) Safety Issue:CNS 3298
