Abstract: The present invention is directed to peptisomes, including nanopeptisomes, which have a perfluorocarbon liquid core containing a perfluorocarbon liquid and a cargo, such as a therapeutically active agent, dispersed in the perfluorocarbon, liquid, and a plurality of amphiphilic peptide molecules surrounding the perfluorocarbon liquid core, wherein the amphiphilic peptide is represented by Formula (I) HB-CL-HP wherein HB is a fluorinated hydrophobic block, such as a fluorinated hydrophobic amino acid sequence. CL is a cross-linking motif and HP is a hydrophilic amino acid sequence. The present invention is also directed to methods of use of the amphiphilic peptides and peptisomes, such as nanopeptisomes, to deliver a cargo, such as a therapeutically active agent, to a cell, Q wherein the cell may be in vitro, ex vi, or in vivo.

Abstract: A hydrogel for delayed release of an anionic macromolecule, wherein the hydrogel comprises the anionic macromolecule, 150 mM NaCl, and a peptide selected from the group consisting of SEQ ID NO:1 through SEQ ID NO:33 in an aqueous medium at a pH of 7.4; wherein the anionic macromolecule has an isoelectric point of at most 6.8; and wherein the hydrogel is capable of retaining at least 25% of the anionic macromolecule after 28-day extraction at 37° C. with a pH=7.4 BTP buffer containing 150 mM NaCl.

Abstract: A peptide comprising the sequence VKVKVRVKVDPPTKVKVRVKV-NH2 forms a hydrogel which has the ability to shear-thin and recover. The hydrogel, both before and after shear-thinning, is capable of killing bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).

Abstract: The present invention provides novel hydrogels and methods of making and using such hydrogels. The present invention provides hydrogels that may be formed by the self-assembly of peptides in solution. Such self-assembly may be brought about by a change in one or more characteristics of the solution. Characteristics of the solution that may be changed include pH, ionic strength, temperature, and concentration of one or more specific ions. In addition, hydrogels of the invention may be disassembled by changing one or more characteristic of the hydrogel such as pH, ionic strength, temperature, and concentration of one or more specific ions.
