Summary
Polymeric nanocarriers enhance photodynamic therapy (PDT) by delivering photosensitizers (PSs) to tumors. These advanced systems activate selectively, improving cancer treatment efficacy and specificity.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Oncology
Background:
- Photodynamic therapy (PDT) uses photosensitizers (PSs) and light to treat diseases, including solid tumors.
- Conventional PDT faces limitations in selectivity and efficacy, necessitating improved delivery systems.
- Hydrophobic PSs often require enhanced water solubility and tumor specificity for effective clinical application.
Purpose of the Study:
- To discuss polymeric nanocarriers for efficient photosensitizer (PS) delivery in photodynamic therapy (PDT).
- To highlight advancements in activatable PS formulations for targeted and enhanced PDT.
- To explore PS-polymer conjugates for improved tumor-specific cancer treatment.
Main Methods:
- Development of polymeric nanocarriers encapsulating photosensitizers (PSs).
- Design of amphiphilic PS-polymer conjugate-based self-quenchable nanoparticles.
- Creation of PS-polymer-conjugate/quencher nanocomplexes for targeted delivery.
Main Results:
- Polymeric nanocarriers improve water solubility and tumor specificity of hydrophobic PSs.
- Self-quenchable nanoparticles and nanocomplexes deliver PSs in an inactive state.
- Tumor environment-sensitive activation mechanisms enable targeted cytotoxic effects.
Conclusions:
- Activatable PS formulations based on PS-polymer conjugates represent a promising platform for efficient and reliable PDT.
- These advanced delivery systems offer enhanced target specificity for photodynamic cancer treatment.
- Further development in this area can overcome current limitations of conventional PDT.

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
