This invention discloses methods and compositions to provide suitable support material for culturing cells with desirable metabolic activity. For example, keratinocytes directly grown on flexible supports show metabolic activity. Wound healing methods and compositions are disclosed using the cells grown on flexible supports, wherein the cells exhibit increased metabolic activity. Cells cultured according to the methods described herein are also useful for cosmetics, for example, treatment post skin peel or dermabrasion, and scar reduction for skin cancer removal, tattoo removal, and for other plastic surgical procedures that require tissue implantation.
Improving immunoassay reliability
US Patent 7771986
Publication Date: Aug. 10, 2010
Assignee: 3M Innovative Properties Co. (St. Paul, MN, USA)
This system and apparatus are useful for detecting a target microorganism or agent and involves a solid support carrying a binding partner specific for the particular microorganism or agent and the solid support being characterized as a means for protecting the binding partner from being dislodged or scraped off of the solid support. The provision of protection against the binding partner being dislodged improves the reliability of tests such as immunoassays being conducted with the solid support and also enables such tests to be automated. Modules and machines for use with the solid support, and the automated conduct of tests are also disclosed.
Molecular color and fluorescent sensory arrays
US Patent Application 20100197516
Publication Date: Aug. 5, 2010
Inventors: Holmes, Andrea (Crete, NE, USA)
Disclosed in this patent is Detechip, a small molecule detection device including a chamber, a carrier within the chamber and a dye in combination with the carrier. The dye is capable of interacting with a small molecule target to produce a detectable change in color, fluorescence, mass uptake, refractive index, extinction coefficient or solubility. A method of using the device is also disclosed. The detection system is compatible with the solubility of many small molecules such as narcotics, which are often presented as salts to ensure water solubility. It is a new spot test device for lab and potential field use that is radically different from current spot tests, as it relies on the interactions between suspect materials and non-toxic dyes rather than functional group reactivity.
