The present invention relates to emulsion-templated silica micro and nano-capsules- and methods for making them. In particular, the template emulsion is stabilized by a biosurfactant that also assists in nucleating the silica shell Mineralizing biosurfactants and stabilized micro- and nano-emulsions useful in forming the emulsion-templated micro- and nano-capsules, and methods for the use of the silica micro- and nano-capsules are also described.

Mineralizing biosurfactant used for nucleating silica

The present invention provides compositions relating to viral capsomeres which comprise foreign immunogenic sequences for use in pharmaceutical compositions and methods of producing such compositions, and related isolated or purified protein and nucleic acid molecules, vectors, host cells, compositions, and methods of use to augment an immune response, immunize an animal and prophylactically or therapeutically treat a disease, disorder or condition. The viral capsomere may be derived from a polyomavirus and comprise an immunogen of interest at the N-terminus and further at the C-terminus and/or at one or more exposed loops of the capsomere.

Immunogenic compositions and methods therefor

The invention relates to nanoemulsions useful for analytical techniques and delivery of cargoes such as pharmaceutically active agents. In particular, the invention relates to nanoemulsions comprising an oil phase dispersed in an aqueous phase and at least two peptide surfactants adsorbed at the liquid-liquid interface, one peptide surfactant comprising a short peptide sequence having &#x3b1;-helical propensity and at least one second polypeptide surfactant comprising at least two peptide sequences having &#x3b1;-helical propensity linked by a linking sequence of 3 to 11 amino acid residues. Optionally the at least one second polypeptide surfactant comprises at least one pharmacokinetic modifying agent and/or a targeting agent. Furthermore, the nanoemulsion may further comprise a cargo such as a pharmaceutically active agent.

Nanoemulsions

An isolated protein comprising a VP1 amino acid sequence wherein one or more exposed loops within said VP1 has an insertion of an amino acid sequence from a virus protein other than VP1, and encoding nucleic acid, are provided. Typically, the virus protein other than VP1 is derived from an influenza virus and in particular, avian influenza virus. The isolated protein may have an insertion of amino acid sequence from a single protein or a plurality of proteins. Also provided are expression constructs, VLPs, pharmaceutical compositions, vaccines and methods of treatment that may be useful in the prophylactic and/or therapeutic treatment of any disease of viral origin, and in particular, influenza virus.

VLP based vaccine delivery system

Methods of modulating interfacial characteristics in a self-assembled, force-transmitting peptide network at a fluid-fluid interface are disclosed. The methods involve exposing a peptide capable of participating in a self-assembled, force-transmitting peptide network, either before or after it interacts with other peptides to form the peptide network to a stimulus that alters the chemical and/or physical properties of the peptide. Use of such methods in applications such as emulsions and foams are also disclosed.

Peptide networks

The present invention provides a method of forming coatings of at least two different coating molecules on at least two electrodes, the method comprising: (a) providing an array of at least two individually-addressable electrodes, (b) allowing a layer of a masking molecule to adsorb onto all electrodes, (c) inducing electrochemical desorption of the masking molecule from at least one but not all electrodes to expose a first set of exposed electrodes, (d) allowing a first coating molecule to adsorb onto the first set of exposed electrodes, (e) exposing all electrodes to a masking molecule to allow adsorption of the masking molecule onto all electrodes, (f) inducing electrochemical desorption of masking molecule from a second set of electrodes to expose a second set of exposed electrodes, (g) allowing a second coating molecule to adsorb onto the second set of exposed electrodes.
