ABSTRACT
OBJECTIVE:
To prepare the Indocyanine green gold nanocages(ICG/Biotin-PEG-AuNC-PCM),and study its anti-tumor activity.METHODS:
Polyol reduction method was used to prepare silver nanometer cubes (AgNC) as template,ion ex-change reaction was used to prepare gold nanocages (AuNC) to characterize its morphology,particle size,near infrared (NIR) light and heat properties. Organic solvent evaporation method was conducted to prepare the ICG/Biotin-PEG-AuNC-PCM loaded with ICG,1-tetradecanol(PCM),surface modification of biotin polyethylene glycol mercapto(Biotin-PEG-SH). Its particle size, polydispersity index (PDI) and drug loading were detected,and in vitro cumulative release (Q) within 180 min under 37,40 ℃was investigated. Using adriamycin-resistant human breast cancer cells(MCF-7/ADR cells)as objects,MTT method was used to in-vestigate the antitumor activities of ICG,ICG/PEG-AuNC-PCM and ICG/Biotin-PEG-AuNC-PCM,and half inhibitory concentra-tion(IC50)was calculated.RESULTS:
AuNC was cubic with particle size of about 60 nm and good light and heat properties. The particle size of ICG/Biotin-PEG-AuNC-PCM was(105±2.8)nm,PDI was 0.261±0.02(n=3). Drug loading was 1.34×108 g/mol AuNC,Q180 min was about 10%under 37℃and Q20 min was about 80%under 40℃. IC50 of ICG,ICG/PEG-AuNC-PCM and ICG/Bi-otin-PEG-AuNC-PCM on MCF-7/ADR cells was 95.2, 29.3, 16.1 μg/mL, respectively.CONCLUSIONS:
ICG/Biotin-PEG-AuNC-PCM is successfully prepared,and the antitumor activity on MCF-7/ADR cells is stronger than ICG.
