Nanoparticles were added in a liquid to prompt the medication release, and it was observed that 5 mg of the medication was released in 1 liter of PBS, which accounted for 60% of the total amount of the drug. While producing an equivalent number of nanoparticles, 5 ml of 10 mg ml−1 of the drug was added. What is the efficiency of encapsulation?
