Abstract:
1. A method of preparing a titanium oxide precipitate having a defined morphology, said method comprising the steps of: (a) providing a peptide, said peptide consisting of 5-20 amino acid residues, wherein said peptide consists of a mixture of amino acid residues that are cationic at neutral pH and amino acid residues that are hydrophilic at neutral pH; (b) providing an aqueous solution comprising a titanium oxide precursor; and (c) combining said peptide and said aqueous solution comprising said titanium oxide precursor, whereby titanium oxide precipitates with a defined morphology; wherein said peptide is selected from the group consisting of KSSKK (SEQ ID NO: 1), SKSKKKSKSKKK (SEQ ID NO: 2), SKKKKKKKKKS (SEQ ID NO: 3), SSKKKKKKKKK (SEQ ID NO: 4), SKSKKKKKKKK (SEQ ID NO: 5), SKKKKSSKKKKS (SEQ ID NO: 6), KKKSKSKKK (SEQ ID NO: 7), SKKKKKSKKKK (SEQ ID NO: 8), SKKKKKSKKKKK (SEQ ID NO: 9), SKKSKKKKKKK (SEQ ID NO: 10), RRRSSRRRSSRRR (SEQ ID NO: 11), SKSKKKSKSKKKSKS (SEQ ID NO: 12), SSKKKSSKKK (SEQ ID NO: 13), RRSSSRRSSSRR (SEQ ID NO: 14), RRRSRRRSRRRSRRR (SEQ ID NO: 15), SKKSKKK (SEQ ID NO: 16), KKSSKKKKKKKKKS (SEQ ID NO: 17), KKKKSSKKKK (SEQ ID NO. 18), SKKSKKKKKKKKK (SEQ ID NO: 19), and SKKKSKKKK (SEQ ID NO: 20).
