Particle dissolution following a 72 h suspension in sterilized water (pH 6.40), complete cell culture medium (BEGM, pH 7.46), or phagolysosome-like buffer (pH 4.55) by ICP-OES. Error bars indicate the mean ± SEM (n = 3). Limit of quantification: 0.0283 μg/mL. Limit of detection: 0.0089 μg/mL, with a maximum of 1.5% dissolved particle measured over 72 h.
