What are liposomes?
Liposomes are spherical vesicles composed of lipid bilayers, used to deliver drugs and other compounds.
How does fluorescence microscopy work?
Fluorescence microscopy uses high-intensity light to excite fluorescent molecules, allowing for visualization of samples.
Why study single liposomes?
Studying single liposomes reveals variations in size and composition that are masked in bulk studies.
Can this method be used for other compounds?
Yes, the method can be adapted for any compound that can be fluorescently labeled.
What is the significance of inhomogeneities in liposomes?
Inhomogeneities can affect the behavior and efficacy of liposomes in drug delivery and other applications.
