Figure 9.
Evaluation of colloidal stability of lyophilized dBSA-UCNP-NOBF4 in different buffers after one year of lyophilization and mixed by vortexing and ultrasonication, based on the results of three repeated size measurements (shown in blue, red, and green) by DLS: (a) in deionized water; (b) in PBS; (c) in DMEM cell culture medium supplemented with 10% FBS; (d) in McCoy’s 5A cell culture medium supplemented with 10% FBS. Gray and/or dotted lines below 100 nm correspond to the presence of proteins and protein aggregates; dotted lines over 300 nm are aggregates.
