Abstract
Official abstract text for this publication.
Discrete micro and nanoscale particles are formed in predetermined shapes and sizes and predetermined size dispersions. The particles can also be attached to a film to form arrays of particles on a film. The particles are formed from molding techniques that can include high throughput and continuous particle molding.
First claim
Opening claim text (preview).
What is claimed is: 1. A delivery device, comprising: a dissolvable substrate of a first material, wherein the dissolvable substrate is dissolvable in biological fluids; and a plurality of substantially monodisperse particles configured from a second material; wherein, each particle of the plurality has (i) an engineered shape bounded by six substantially planar surfaces that each span respective entire sides of the particle and (ii) a maximum cross-sectional dimension of less…
