Specifically, a mixture of 15 mg soyphosphatidylcholines (PC), 5 mg cholesterol, 0.6 mg DSPE-PEG2000,0.3 mg DSPE-PEG-PBA, and 0.1 mg DSPE-PEG-DBCO wasdissolved in a methanol/chloroform solution (1:3, v/v) within around-bottom flask. The solvent was evaporated using a rotaryevaporator to form a thin lipid film on the flask's inner surface,followed by vacuum desiccation to ensure complete removal ofresidual solvents. The resulting lipid film was rehydrated with 4 mLof PBS containing 2 mg TMZ under ultrasonication. Therehydrated suspension was then passed 11 times through apolycarbonate membrane (200 nm) using an Avanti Mini-Extruderto obtain uniform liposomes. Thereafter, MA (20 mg, 0.06 mmol)was added to the liposome solution, which was subsequentlyincubated on a shaker overnight to promote the chemical reactionbetween PBA and MA. This resulted in the formation of pHresponsive borate ester bonds (PBA-MA), culminating in thesynthesis of the final Bioorthosome. Control liposomes weresynthesized employing the same methodology, specificallyincluding the DBCO-MA Lipo, which is devoid of pHresponsiveness and bioorthogonal chemistry shielding, as well asthe DBCO-PBA Lipo, which lacks glucose functionality on itssurface. For in vitro studies, rhodamine B (RhB) was encapsulated,while indocyanine green (ICG) was incorporated for in vivobiodistribution analysis across all liposome groups.
