Methods for producing gas microbubbles having lipid-containing shells formed thereon

摘要

A method for producing a gas microbubble comprises subjecting the gas microbubble to isothermal conditions or cooling conditions such that the lipid-containing shell cools at a rate ranging from about 100° C./min. to about 103° C./min., and wherein said subjecting step transforms the lipid-containing shell from a liquid state to a solid state.
