  • Publication number: 20110286915
    Abstract: The present invention provides a nanocarrier having an interior and an exterior, the nanocarrier comprising at least one conjugate, wherein each conjugate includes a polyethylene glycol (PEG) polymer. Each conjugate also includes at least two amphiphilic compounds having both a hydrophilic face and a hydrophobic face. In addition, each conjugate includes an oligomer, wherein at least 2 of the amphiphilic compounds are covalently attached to the oligomer which is covalently attached to the PEG. The nanocarrier is such that each conjugate self-assembles in an aqueous solvent to form the nanocarrier such that a hydrophobic pocket is formed in the interior of the nanocarrier by the orientation of the hydrophobic face of each amphiphilic compound towards each other, and wherein the PEG of each conjugate self-assembles on the exterior of the nanocarrier.

  • Patent number: 7291456
    Abstract: The invention includes a method for determining the differences between the molecular interactions of two different mixtures of molecules and identifying ligands specific for molecules in one mixture. The method utilizes a combinatorial library to compare the molecular interactions of the two mixtures and eliminates those interactions that are common to both mixtures and those that are unique to the first mixture, such that interactions essentially unique to the target mixture are identified. Ligands specific for molecules in the target mixture can then be identified. The invention also includes a method of screening a combinatorial library to distinguish between true positive beads and false positive beads and to provide for the identification of ligands specific for target molecules.

  • Patent number: 7262269
    Abstract: The invention includes a cell-growth-on-bead assay for screening a one-bead-one-compound combinatorial bead library to identify synthetic ligands for cell attachment and growth or proliferation of epithelial and non-epithelial cells. Cells are incubated with a compound bead library for 24 to 72-hours, allowing them to attach and grow on the beads. Those beads with cells growing are removed, and the ligand on the bead is identified. Also provided are ligands specific for cancer cells.
