Lipid Membrane Structure and Behavior

Bubbling over: After endocytosis and intracellular trafficking to lysosomes, liposomes containing ammonium bicarbonate can be thermally triggered to generate CO2 bubbles (see scheme). These bubbles grow rapidly and collapse violently to induce transient cavitation, a process that can disrupt the lysosomal membrane and release lysosomal proteases, thus leading to cell necrosis.
