Claim Text:
1. A method for making a YCWP-NP delivery system, comprising yeast cell wall particles (YCWPs) comprising nanoparticles (NPs) having at least one dimension of about 1-40 nm contained within the interior of the YCWPs, the method comprising the steps of: (a) loading the NPs into the YCWPs, wherein the loading comprises incubating a suspension comprising YCWPs and NPs for a time sufficient for the NPs to enter into the YCWPs, (b) drying the material resulting from (a), (c) optionally repeating steps (a)-(b) at least once, (d) resuspending the YCWPs and nanoparticles in a solvent for a time sufficient for additional NPs to enter into the YCWPs, (e) optionally drying the material resulting from (d), and (f) optionally trapping the NPs in the YCWPs using an appropriate trapping means, such that the YCWP-NP delivery system is made; wherein the NPs are insoluble in water.
