Abstract: An objection is to provide a method for characterizing a molecule delivery particle, the method comprising determining a molar concentration thereof.
The method for characterizing a molecule delivery particle, the method comprising subjecting a molecule delivery particle comprising a first particle and a second particle to particle separation with optical measurement to determine an increment in refractive index of each of the first particle and the second particle; and determining a molar concentration of each of the first particle and the second particle based on the increment in refractive index, a molecular weight, and a specific refractive index increment of each of the first particle and the second particle.
