  • Nanoparticles as delivery vehicles of active ingredients and methods for the production thereof
    Patent number: 11344499
    Abstract: A nanoparticle comprising a keratin polypeptide and at least one lipophilic active ingredient, wherein the at least one lipophilic active ingredient is non-covalently bound to the keratin polypeptide and can be e.g. a therapeutic or diagnostic agent, a nutraceutical, a cosmetic ingredients, a dye or a cosmeceutical, the keratin polypeptide being water-soluble; optionally, the nanoparticle further comprises at least one hydrophilic active ingredient non-covalently bound to the keratin polypeptide, which can be e.g. a therapeutic or diagnostic agent, a nutraceutical, a cosmetic ingredients, a dye or a cosmeceutical.

  • Oligonucleotide Probes
    Publication number: 20090137789
    Abstract: Fluorescent oligonucleotide probe having a general formula (I), wherein Onu represents an oligonucleotide residue, Thion represents a fluorescent oligothiophene containing n thiophenic rings, n being an integer lower than 8, L representing a binder conceived to maintain Thion mobile in relation to Onu in a manner so that Thion can perform its fluorescent action correctly, and Onu can perform its hybridization action. (I)=Onu-L-Thion.

  • Functionalized thiophene oligomers and their use as fluorescent markers
    Patent number: 6841669
    Abstract: Thiophene oligomers which are excitable in the visible and ultraviolet region and each having at least one functional group able to form a covalent bond with organic and/or biological molecules, so as not to alter either the fluorescence properties of the oligomers or the biological activity of the bound molecules, and their use as fluorescent markers in analysis techniques.
