Selection of products

Most products in this inventory satisfy three criteria:

1. They can be readily purchased by consumers, and
2. They are identified as nano-based by the manufacturer OR another source, and
3. The nano-based claims for the product appear reasonable.

In every instance, we have tried to identify specific products from specific producers. However, since nanotechnology has broad applications in a variety of fields, we have included a number of “generic” products that you can find in many places on the market such as computer processor chips. These are clearly labeled in the inventory. In some cases, companies offer several similar nanotechnology-based products and product lines. To reduce redundancy, we have just included a few samples in this inventory and hope that they will provide an initial baseline for understanding how nanotechnology is being commercialized.

There are probably some products in the inventory which producers allege are “nano,” but which may not be. We have made no attempt to verify manufacturer claims about the use of nanotechnology in these products, nor have we conducted any independent testing of the products. We have tried to avoid including products that clearly do not use nanotechnology, but some have undoubtedly slipped through.

Finally, some products are marked “Archive” to indicate that their availability can no longer be ascertained. When these products were added to the inventory we included live links, but since then the company may have discontinued the product, gone out of business, removed a self-identifying “nano” claim or simply changed their web address. In these instances we have attempted to locate a cached version of the product website using The Internet Archive.
