Poly (methyl methacrylate-co-methacrylic acid) (PMMA-MA, 1.3% methacrylic acid, Mn ∼15000, Mw ∼34000), acetonitrile (anhydrous, 99.8%), rhodamine B octadecyl ester perchlorate (>98.0%), lithium tetrakis(pentafluorophenyl)borate ethyl etherate were purchased from Sigma-Aldrich. DiD oil (1,1'-dioctadecyl-3,3,3',3'-tetramethylindodicarbocyanine perchlorate) (Cy5) and quantum dots QD655 were purchased from Life-Technologies. Sodium phosphate monobasic (>99.0%, Sigma-Aldrich) and sodium phosphate dibasic dihydrate (>99.0%, Sigma-Aldrich) were used to prepare 20 mM phosphate buffers at pH 5.8-9.0. Milli-Q water (Millipore) was used in all experiments.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
