PDLLA-Rhodamine (PDLLA-RhB), MW 5K is a rhodamine-functionalized poly(DL-lactide) with a molecular weight of approximately 5K. It combines a low-molecular-weight, biodegradable amorphous PDLLA backbone with a fluorescent rhodamine label specifically for fluorescence imaging, polymer tracking, nanoparticle visualization, drug delivery research, and biomaterial studies.
Key Features and Benefits
- Rhodamine-Functionalized PDLLA: Combines biodegradable poly(DL-lactide) with a fluorescent rhodamine label for visualization and tracking.
- MW 5K: Provides a low molecular weight with good processability specifically for polymer formulation, particle preparation, and imaging research.
- Fluorescent Label: Rhodamine provides fluorescence for detecting and tracking PDLLA-containing materials in compatible experimental systems.
- Biodegradable Polyester: The PDLLA backbone contains hydrolyzable ester linkages that specifically support gradual polymer degradation under appropriate conditions.
- Amorphous PDLLA Backbone: The random distribution of D- and L-lactide units limits crystallization and provides an amorphous polymer structure.
- Good Processability: The lower molecular weight facilitates polymer dissolution, formulation, and processing compared with higher-molecular-weight PDLLA grades.
- Polymer Tracking: The fluorescent label enables visualization of polymer distribution, localization, and material behavior in research applications.
Applications
- Fluorescence Imaging: Supports visualization and detection of PDLLA-based materials using compatible fluorescence imaging techniques.
- Polymer Tracking: Enables research on polymer distribution, localization, transport, and degradation behavior.
- Nanoparticle Visualization: Supports fluorescent visualization of PDLLA-based nanoparticles and related delivery systems.
- Drug Delivery Research: Enables tracking of polymer carriers in drug-delivery and controlled-release studies.
- Particle Formulation: Supports preparation of fluorescent PDLLA microparticles, nanoparticles, and related polymer systems.
- Material Distribution Studies: Provides a fluorescent marker for studying the distribution and localization of PDLLA-containing materials.
- Biomaterial Research: Supports development and evaluation of fluorescent biodegradable polymers, particles, coatings, composites, and related biomaterials.
Storage and Handling
- Storage: Store at –20 °C in a tightly sealed container under dry conditions. Protect from moisture and light.
- Handling: Minimize exposure to light to reduce photobleaching of the fluorescent label. Protect from moisture and excessive heat. Allow the material to equilibrate to room temperature before opening to minimize moisture condensation.
