Nanoparticulates with drug release based on temperature change

Area of Science:

• Biomedical Engineering
• Materials Science
• Pharmacology

Background:

• Stimuli-induced release systems offer controlled drug delivery in response to external triggers.
• Thermo-responsive systems are designed to release drugs based on temperature variations.
• These systems are particularly relevant for cancer treatment modalities like hyperthermia.

Purpose of the Study:

• To review recent advancements in thermo-responsive drug delivery systems.
• To categorize different types of thermo-responsive drug delivery platforms.
• To highlight the application of these systems in targeted cancer therapy.

Main Methods:

• Literature review of thermo-responsive drug delivery systems.
• Categorization based on system type (hydrogels, liposomes, nanoparticles, conjugates).
• Focus on thermo-sensitive polymers like poly-(N-isopropyl-acrylamide).

Main Results:

• Thermo-responsive systems can be physical, chemical, or biological in nature.
• Liposomes exhibit inherent temperature sensitivity.
• Other systems commonly employ thermo-sensitive polymers, such as poly-(N-isopropyl-acrylamide).

Conclusions:

• Thermo-responsive drug delivery holds significant potential for controlled therapeutic release.
• The choice of system (e.g., liposomes, nanoparticles) depends on specific application requirements.
• Poly-(N-isopropyl-acrylamide) is a key material in developing advanced thermo-responsive drug delivery platforms.
