Abstract: A retail sales system and method for using same are provided. The system may include a mobile in-store terminal having a processor configured to execute a software application configured to receive product search information relating to a requested product, a database configured to store product detail information for a plurality of products, and a server configured to receive the product search information from the mobile in-store terminal, identify one or more products corresponding to the product search information, obtain and provide product detail information related to each of the one or more identified products to the mobile in-store terminal. The mobile in-store terminal may receive product search information that includes a product image of the requested product, a unique visual code corresponding to the requested product, a text code corresponding to the requested product, and a text description corresponding to the requested product.

Abstract: Novel magnetically responsive hydrophilic protein or polypeptide microspheres prepared by dispersing an aqueous solution or dispersion of protein or polypeptide and particulate magnetically responsive material in an organic solvent solution of a high molecular weight polymer to form a stabilized dispersion of microspheres and cross-linking said microspheres with a polyfunctional cross-linking agent.
