  • Publication number: 20130136697
    Abstract: The invention discloses injectable hydrogels which are in the form of crosslinked nano beads or particle in the size range 5 nm to 10 ?m, comprising PAMAM dendrimer with asymmetrical peripheral end groups such that one of the terminal groups is involved in formation of hydrogel and the other in involved in the conjugation of drugs or imaging agents and their methods of preparation. The said gel is formed by reaction of the PAMAM dendrimer with asymmetrical end groups with other polymer wherein the other polymer is selected from the group of linear, branched, hyperbranched or star shaped polymers with functionalized terminal groups. The PAMAM dendrimer with asymmetrical terminal groups consists of a Generation 2 and above PAMAM dendrimer with symmetrical end groups modified using the amino acids or their modified forms.

  • Patent number: 5313320
    Abstract: A method for converting an opaque portion of a side-group liquid crystalline polymer body into a transparent portion. The method involves applying sufficient shear force to the polymer body for a sufficient time to convert the opaque portion into a transparent portion. The method provides for erasure of opaque optical pixels from data storage disks without requiring the use of electrical or magnetic fields.
