Fluorescent Liposomes

CD Bioparticles’ products with deep understanding of the strategies and the applications of various of delivery cargos with precise designs and advanced technical platforms can help you to solve:

The challenges you might meet:

• Limited options for tracking and detection of fusion, pore forming, and cell uptake (e.g. macrophage) experiments
• Hard to track and image the distribution of the liposomes
• Limited wavelength coverage for your tracking and detection experiments
• Issue of quenching or fluorescence compensation
• Non-active fluorescent liposomes which cannot be conjugated with other molecules
• Tedious chemical synthesis, formulation, and purifications
