(A) PLGA microparticles with average diameter of 2.7 µm loaded with 8.9, 22.9 and 42.9 mM of MB. (B) Magnitude and (C) phase and (D) complex B-scans of MB-PLGA particles suspended in 200 µm capillary tubes. (E) CNR values at the magnitude, phase and complex images for each batch of PLGA-MB microparticles. (F) Number of pixels with CNR greater than the established threshold (CNR≥4).
