Summary
Natural biomaterials offer improved biocompatibility and delivery for photosensitizers in photodynamic therapy (PDT). This review explores their use in cancer treatment, enhancing efficacy and reducing side effects.
Area of Science:
- Biomaterials Science
- Oncology
- Nanomedicine
Background:
- Photodynamic therapy (PDT) is a cancer treatment with limitations due to poor solubility and tumor selectivity of conventional photosensitizers (PSs).
- Natural biomaterials are emerging as promising alternatives due to their biocompatibility, low toxicity, and stimuli-responsive properties.
- These materials can enhance the delivery efficiency of PSs for improved therapeutic outcomes.
Purpose of the Study:
- To review recent advancements in natural biomaterials for formulating and delivering photosensitizers in photodynamic therapy for cancer treatment.
- To discuss the advantages of specific natural biomaterials like oligosaccharides, biopolymers/proteins, and extracellular vesicles as drug delivery platforms.
- To outline strategies for designing and modifying natural biomaterial-based systems to optimize cancer PDT.
Main Methods:
- Literature review of recent research on natural biomaterials in photodynamic therapy.
- Analysis of formulation strategies for photosensitizers using natural materials.
- Discussion of design and functional modification approaches for biomaterial-based delivery systems.
Main Results:

01:24Site-Targeted Drug Delivery Systems: Polymeric Carriers
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. Monoclonal...
01:24Modified-Release Drug Delivery Systems: Site-Targeted
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.
01:27Bioavailability Enhancement: Drug Permeability Enhancement
After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt secretion,...
01:16Bioavailability Enhancement: Drug Solubility Enhancement
Bioavailability is a critical factor in determining a drug's effectiveness. It refers to the proportion of a drug that enters the circulation when introduced into the body and is, as a result, able to have an active effect. Enhancing bioavailability is essential for drugs with poor solubility, as it can significantly impact their therapeutic efficacy. Various methods are employed to increase the solubility of drugs, thereby enhancing their bioavailability.Micronization and nanonization are...
01:05Bioavailability Enhancement: Drug Stability Enhancement and GI Retention
Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...
