Summary
Self-luminous probes, like chemiluminescent and bioluminescent types, offer superior imaging by generating their own light. This review explores their mechanisms, applications in detecting biomarkers and reactive oxygen species (ROS), and future potential in medicine.
Area of Science:
- Biomedical Engineering
- Analytical Chemistry
- Materials Science
Background:
- Self-luminous probes, including chemiluminescent and bioluminescent systems, generate light via chemical or enzymatic reactions.
- Unlike photoluminescent probes, they do not require external excitation, which reduces autofluorescence and improves signal-to-noise ratios in biological imaging.
- These probes are increasingly utilized for detecting diverse analytes such as biomarkers, reactive oxygen species (ROS), and heavy metals.
Purpose of the Study:
- To systematically review the luminescence mechanisms and structure-activity relationships of contemporary self-luminous probes.
- To highlight recent advancements in their biomedical applications, focusing on detection, imaging, and theranostics.
- To discuss emerging trends and future prospects for developing novel multifunctional materials.
Main Methods:
- Literature review and systematic analysis of current self-luminous probe technologies.
- Examination of luminescence mechanisms and structure-activity relationships.
- Compilation and synthesis of recent biomedical applications and emerging trends.
Main Results:
- Self-luminous probes offer distinct advantages over photoluminescent probes due to their intrinsic light generation.
- Significant progress has been made in applying these probes for sensitive detection and high-contrast imaging of various biological and chemical species.
- The review identifies key structure-activity relationships guiding the design of improved probes.
Conclusions:
- Self-luminous probes are versatile tools with expanding roles in biomedical research and clinical diagnostics.
- Further development in materials science is expected to yield novel probes with enhanced functionalities for theranostics and multifunctional applications.
- Increased adoption in research and clinical settings is anticipated, driven by their superior imaging capabilities and reduced artifacts.
