Abstract
A sac is produced by use of a compound which includes a hydrophobic portion and a polar group which is hydrolyzable by an enzyme and which is spaced from the hydrophobic portion by a hydrophilic portion which does not have a polarity sufficient to form a vesicle. A detectable marker may be released from the sac by use of a hydrolase enzyme, whereby the sac may be used as a substrate in an enzyme assay.
