Photoresponsive systems offer precise control over drug and gene delivery using light. This review covers direct and indirect light-activated systems for enhanced therapeutic outcomes and safety.
Area of Science:
- Biomedical Engineering
- Materials Science
- Pharmacology
Background:
- Light offers precise control over external stimuli like time, site, wavelength, and density.
- Photoresponsive drug/gene delivery systems are crucial for spatiotemporal control, enhancing therapeutic efficacy and safety.
Purpose of the Study:
- To review recent advancements in photoresponsive drug/gene delivery systems.
- To categorize and discuss different types of photoresponsive delivery mechanisms.
Main Methods:
- Summarized research on direct photoresponsive systems (vehicle/drug photoreactions).
- Detailed indirect photoresponsive systems triggered by light-generated mediators (heat, ROS, hypoxia, gas).
- Compiled materials and chemical structures responsive to UV, visible, and NIR light.
Main Results:
- Identified two major categories: direct and indirect photoresponsive systems.
- Highlighted various materials and structures for UV, visible, and NIR light responsiveness.
- Emphasized the role of mediators like heat, ROS, hypoxia, and gas in indirect systems.
Conclusions:
- Photoresponsive systems provide advanced spatiotemporal control for drug/gene delivery.
- Direct and indirect systems offer distinct mechanisms for light-triggered release.
- Future research should address challenges and explore new applications in this field.
