Abstract

The present invention concerns drug delivery particles which can prevent interaction between a biologically-active cargo comprised within the particles and components of an aqueous environment in which said particles are present. The particles are sensitive to p H such that above a threshold p H level the biologically-active cargo becomes accessible to the surrounding environment. Such particles are accordingly useful for stably storing a biologically-active cargo in an aqueous composition containing components which would otherwise interact deleteriously with the cargo, and releasing the cargo to mediate a biological effect in the body of an animal, such as a human, to which the composition is administered. Also provided are compositions comprising such particles, as well as methods for making and using such particles and compositions.

Abstract

Materials and methods for performing microscopy include applying a curable liquid polymer to a surface or structure to be characterized and polymerizing the polymer. The polymerized polymer represents a mold of the structure or surface and can be analyzed without disrupting the surface or structure needing characterization. The materials also do not leave a residue or otherwise alter a surface chemistry of the structure characterized.
