Abstract
Gold nanoparticles with large size exhibit preferable properties for photothermal therapy (PTT). However, the prolonged tissue retention and slow elimination of gold nanoparticles limit their therapeutic applications. Previously, gold nanoclusters carrying lipid nanoparticles (Au-LNPs) have been reported after simply mixing Au3+ with preformed diethylenetriaminepentaacetic acid lipid nanoparticles to solve this contradiction. Au-LNPs demonstrated enhanced photothermal effects in comparison to neat gold nanoparticles. To further improve the photothermal activity, we introduced the organic photothermal agent boron dipyrromethene (BODIPY) to Au-LNPs for synergistic PTT. Au- and BODIPY-grafted LNPs (AB-LNPs) were formed by simply mixing Au-LNPs with BODIPY. The BODIPY could be associated stably to Au-LNPs, and the release of BODIPY from AB-LNPs could be accelerated by laser irradiation. AB-LNPs are scalable and showed excellent photothermal effects. AB-LNPs showed enhanced cellular uptake efficiency compared to free BODIPY in 4T1 breast cancer cells. Under laser irradiation, AB-LNPs exhibited synergistic photothermal effects with significantly reduced dosage compared to monotherapy (treatments with Au-LNPs or free BODIPY alone). This study thus provides a facile and adaptive strategy for the development of a scalable and safe high-performance nanoplatform for synergistic PTT in the treatment of cancer and other diseases.

J Colloid Interface Sci 2022; 627:596-609. [PMID: 35872417 DOI: 10.1016/j.jcis.2022.07.084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 07/12/2022] [Accepted: 07/13/2022] [Indexed: 10/17/2022]
Abstract
Photothermal therapy (PTT) and sono-photodynamic therapy (SPDT) are fast growing local treatment modalities with minimal invasiveness and high safety. Gold nanoparticles and indocyanine green (ICG) have been used as sensitizers for PTT and SPDT. However, long resident time of gold nanoparticles in tissues and fast elimination of ICG hampered their further clinical applications. Herein, we developed nanocapsules formed by hyaluronic acid and chitosan loading with ICG and tiny gold nanoclusters (TAuNCs) to overcome the shortcomings of gold nanoparticles and ICG for combined PTT and SPDT. The nanocapsules exhibited good biological stability, favorable photothermal effects, and ultrasound/near-infrared light (NIR)-responsive release behaviors. The hyaluronic acid could mediate the specific delivery of cargos to CD44 protein over-expressing cancer cells. The in vitro and in vivo results showed that TAuNCs and ICG could act synergistically to obtain satisfactory anticancer effects under NIR laser and/or ultrasound exposure induced by thermal ablation and reactive oxygen species (ROS) generation. Biodistribution and excretion studies showed that the nanocapsules had longer ICG retention time in tumor and most of the TAuNCs could be effectively excreted from the body within one month. This study thus provides a facile strategy for the development of a safe and high-performance nanoplatform for synergistic PTT/SPDT.
