Here, we investigate the use of an online microdroplet calibration system to size NPs in a single step. SPED marked with 3 different DNA sequences (SPED1-SPED3) were introduced at 3 different points of the consecutive 13 touch sites of a patient-care scenario that was repeated 3 times, resulting in a total of 288 values. In this way, the microdroplet calibration standards are automatically matrix matched with the NP-containing solution. When NPs are suspended in a complex medium, the matrix may affect the analyte sensitivity and lead to inaccurate NP sizing. DNA synthesis for true random number generation, Linda C.
