    Abstract: A method of preparing spray dried particles for inhalation comprising providing: (i) an aqueous liquid composition including the alginate oligomer and an aqueous liquid composition including an anti-adherent compound, or (ii) an aqueous liquid composition including the alginate oligomer and an anti-adherent compound; providing an organic liquid composition including a phospholipid; combining a volume of the organic liquid composition with a volume of the aqueous liquid composition, wherein the total volume of the organic liquid composition is smaller than the total volume of the aqueous liquid composition with which it is combined, and wherein the total volume of aqueous liquid composition and said total volume of organic liquid composition are sufficient to provide a combination; homogenizing the combination to form an organic-in-aqueous liquid emulsion for spray drying; and spray drying the organic-in-aqueous liquid emulsion to form the spray dried particles for inhalation.

    Abstract: A method for translocating a cationic micro/nanoparticle across a mucus layer, the method including (a) contacting the mucus layer with at least one alginate oligomer, the alginate oligomer having at least 70% mannuronate residues, together with the cationic micro/nanoparticle; or (b)(i) contacting the cationic micro/nanoparticle with an alginate oligomer having at least 70% mannuronate residues thereby forming a micro/nanoparticle carrying the alginate oligomer, and (b)(ii) contacting the mucus layer with the micro/nanoparticle prepared in step (b)(i). There is also provided a method for translocating a molecule of interest across a mucus layer including contacting the mucus layer with a micro/nanoparticle which is formed of self-assembling micro/nanoparticle forming components, wherein at least one is a cationic micro/nanoparticle forming agent and at least one is an alginate oligomer which has at least 70% mannuronate residues, and further comprises the molecule of interest, optionally wherein the molecule of interest is covalently bound to one or more of the self-assembling micro/nanoparticle forming components.

    Abstract: The disclosure relates to an alginate oligomer of 2 to 75 monomer residues, wherein said monomer residues do not carry a sulphate group, for use as a blood anticoagulant in clinical and non-clinical applications, including in vivo, ex vivo and in vitro contexts. The invention further provides for the use of such an alginate oligomer in preparing a product or device having a reduced capacity to promote blood coagulation, wherein said alginate oligomer is provided at or on a surface of said product or device. Such products and devices form a further aspect of the invention.

    Abstract: A bacitracin-alginate oligomer conjugate including a bacitracin-class antibiotic connected covalently to at least one alginate oligomer via a direct covalent bond or a covalent molecular linker, or a pharmaceutically acceptable salt, solvate, hydrate, diastereoisomer, tautomer, enantiomer or active metabolite thereof. Also provided are methods for the preparation of the conjugate, pharmaceutical compositions comprising the conjugate and the use thereof in a method for the treatment or prevention of a bacterial infection in a subject with, suspected to have, or at risk of, a bacterial infection.
