SD-TDA: A Breakthrough for Measuring Encapsulation Efficiency

SD-TDA: A Breakthrough for Measuring Encapsulation Efficiency

SD-TDA analyzes size distribution to determine encapsulation efficiency without separation. Free agents appear as molecular-sized, while encapsulated ones match nanoparticle size. The ratio of their areas under the curve quantifies efficiency. This fast, precise method also assesses purification steps, enhancing drug delivery analysis and nanoparticle-based therapeutic development.
