Poly styrene co maleic anhydride psma

Poly (styrene‐co‐maleic anhydride) (PSMA, Mn = 1700) and anhydrous tetrahydrofuran (THF, 99.9%) were purchased from Sigma‐Aldrich. Poly [(9,9‐dioctylfluorenyl‐2,7‐diyl)‐co‐(1,4‐benzo‐{2,1,3}‐thiadiazole)] (PFBT, MW = 10 000, polydispersity 1.7) was obtained from ADS Dyes (Quebec, Canada). Octaarginine peptides were purchased from Jie Li Bio. HeLa cell lines were purchased from Cell Bank of Chinese Academy of Sciences (Shanghai). Minimum essential media (MEM), Dulbecco's modified Eagle's medium (DMEM) and foetal bovine serum (FBS) were from Gibco, Invitrogen. Chlorpromazine (CPZ), methyl‐β‐cyclodextrin (mβCD) and EIPA were purchased from Sigma‐Aldrich (St. Louis, MO, USA). RFP‐LAMP1 plasmid was acquired from Addgene (plasmid # 1817).

Poly (9,9-dioctylfluorene-2,7-diyl) (PFO) and poly (styrene-co-maleic anhydride) (PSMA) were purchased from Sigma-Aldrich. Tetrahydrofuran (THF; anhydrous, ≥99.9%, inhibitor-free), diphenylcarbazide (DPC), K₂Cr₂O₇, NaCl, MgCl₂, KCl, CaCl₂, FeCl₃ 6H₂O, CuCl₂ 2H₂O, NiCl₂, KMnO₄, acetic acid, boric acid, phosphoric acid, HCl and NaOH were obtained from Sinopharm Chemical Reagent Co., Ltd. (Shangai, China).
The apparatus used in the work included a transmission electron microscope (Talos F200X G2, Thermo Fisher, Waltam, MA, USA); dynamic light scattering system (DLS, Malvern Zetasizer Nano ZS, Malvern, United Kingdom); U-3900 ultraviolet–visible (UV–vis) spectrophotometer (Hitachi, Japan); F-7000 fluorescence spectrophotometer (Hitachi, Japan) and Laser Scanning Confocal Microscopy (Carl Zeiss, Germany).
