US Patent:

6649138, Nov 18, 2003

Filed:

Apr 23, 2001

Appl. No.:

09/841237

Inventors:

Edward William Adams - San Francisco CA

Assignee:

Quantum Dot Corporation - Hayward CA

International Classification:

B32B 516

US Classification:

423403, 428407

Abstract:

Water-dispersible nanoparticles are prepared by applying a coating of a multiply amphipathic dispersant to the surface of a hydrophobic nanoparticle comprised of a semiconductive or metallic material. The multiply amphipathic dispersant has two or more hydrophobic regions and two or more hydrophilic regions, and is typically polymeric. Preferred polymeric dispersants are comprised of (1) a hydrophobic backbone with hydrophilic branches, (2) a hydrophilic backbone with hydrophobic branches, or (3) a backbone that may be either hydrophobic or hydrophilic, and substituted with both hydrophilic and hydrophobic branches. Monodisperse populations of water-dispersible nanoparticles are also provided, as are conjugates of the water-dispersible nanoparticles with affinity molecules such as peptides, oligonucleotides, and the like.

Filed:

Appl. No.:

5/656413

Inventors:

Michael J. Meier - Monrovia CA
Edward C. Adams - La Palma CA
Richard W. Lindberg - Garden Grove CA

Assignee:

McDonnell Douglas Corporation - Long Beach CA

International Classification:

H04H 538

US Classification:

358166

Abstract:

An image formed on an array of photosensitive elements is scanned and stored. A defocussed image is scanned and subtracted from the stored signals. The frame-to-frame subtractive algorithm permits simultaneous image enhancement and elimination of sensor induced noise. Required storage capacity is reduced by separately storing the high frequency information-bearing components and the low frequency components of the video.
