What are thermosensitive liposomes?
Thermosensitive liposomes are liposomes that release their contents in response to temperature changes.
How does the staggered herringbone micromixer work?
It creates a chaotic mixing environment that enhances the mixing of lipids and drugs at the nanoscale.
What is the significance of co-encapsulation?
Co-encapsulation allows for simultaneous delivery of therapeutic agents and imaging agents, improving treatment monitoring.
What is photothermal-triggered release?
It is a method where light is used to heat liposomes, triggering the release of their contents.
What are the advantages of using microfluidics?
Microfluidics provides precise control over the preparation process and allows for high-throughput production.
