Patent ID: 7998923

Claim:
A bioactivated particle, comprising: a quantum dot that includes a surface; and at least one bioactivation peptide attached to said surface of said quantum dot, said bioactivation peptide comprising a molecular recognition part that is bound to the surface of said quantum dot and one or more functional parts, said molecular recognition part comprising an amino-end and a carboxy-end and comprising one or more hydrophobic spacers and one or more binding clusters and wherein said functional part(s) is attached to said molecular recognition part at said amino-end and/or said carboxy-end, wherein said binding cluster is directly bound to said surface of said quantum dot and comprises an amino acid independently selected from the group consisting of cysteine, methionine, and histidine, wherein said hydrophobic spacer comprises an amino acid modified to be hydrophobic independently selected from the group consisting of cyclohexyl-substituted alanine, cyclohexyl-substituted glycine, cyclohexyl-substituted isoleucine, cyclohexyl-substituted leucine, cyclohexyl-substituted methionine, cyclohexyl-substituted arginine, cyclohexyl-substituted valine, and cyclohexyl-substituted tryptophan, wherein said bioactivation peptide comprises the sequence Cha-C-C-Cha-C-C-Cha-C-C-Cha [SEQ. ID. NO. 1], and wherein Cha is cyclohexyl alanine and C is cysteine.
