Figure 3From: Process and formulation variables in the preparation of injectable and biodegradable magnetic microspheresEffect of formulation variables in oil phase. (A) Effect of PLGA concentration in oil phase on average microsphere diameter (â–ª, y-axis is to the left) and the relationship between PLGA concentration and kinematic viscosity (â—‹, y-axis is to the right). (B) Effect of oil phase volume on average microsphere diameter (â–², y-axis is to the right).Back to article page
