What are exosomes?
Exosomes are small extracellular vesicles that play a role in cell communication and have potential therapeutic applications.
How do microneedles improve drug delivery?
Microneedles can penetrate the skin or other biological barriers, allowing for localized and efficient delivery of drugs or therapeutic agents.
What challenges do exosomes face in clinical applications?
Exosomes often have stability issues and can be rapidly cleared from the body, limiting their effectiveness.
What is the significance of dry-state preservation?
Dry-state preservation enhances the stability of exosomes, making them easier to store and transport.
Can microneedles be used for home treatment?
Yes, the convenience of microneedle delivery systems makes them suitable for both clinical and home use.
