To increase the pore size of the skin and facilitate drug diffusion.
What is the key characteristic of hydrogels that makes them useful for drug delivery?
Their three-dimensional, cross-linked network structure.
Which of the following is NOT a type of microneedle drug delivery system mentioned in the text?
Dissolving microneedles
What is the primary function of the piezoelectric crystal in a vibrating-mesh nebulizer?
To oscillate the metal mesh and force the drug liquid through the holes.
