The dyes (methyl violet / malachite green /….) is used as a drug to evaluate the drug release behaviour of the alginate particles. A number of the particles are placed in a solution which mimics the high pH of the stomach or the low pH of the and samples are drawn at specified time intervals and the amount of methyl violet / malachite green is determined using a UV/vis spectrophotometer.
