Bespoke nanostars: synthetic strategies, tactics, and uses of tailored branched gold nanoparticles

“…Li et al utilized hollow spiked gold nanoshells for chemo-thermal antitumor therapy. 185 The chitosan-functionalized-liposome-based shells were synthesized by locking AuCl 4 − anions with charged ammonium species from chitosan, which when reduced formed a branched gold coating. The overgrowth of gold nanorods through kinetic control by CTAC and selective surface blocking by Ag UPD was able to lead to gold nanoarrows consisting of two pyramidal heads and a four-wing shaft.…”

Synthesis and degradation mechanism of renally excretable gold core–shell nanoparticles for combined photothermal and photodynamic therapy

“…28,29 Gold ion seeding method/seedless method, on the other hand, is a fed-batch process in which the gold salt is directly reduced on the core in the presence of a reducing agent such as ascorbic acid. 30 This in situ reduction method is a one-pot facile process and the optical property of the resultant nanoparticles can be easily tuned by changing the aspect ratio of the core and shell by merely varying the concentration of the template, gold salt, and reducing agent used. 31 The simplicity and ability for scalable synthesis make one-pot seedless growth methods highly popular.…”

Catalase-like nanosystem for interlocking trimodal cancer therapy with hypoxia relief

“…In addition, Au nanomaterials are state-of-the-art efficient photothermal agents that exhibit the superior capability of photothermal conversion in PTT with the unique optical property of surface plasmon resonance in the NIR region and good biocompatibility [25]. According to our previous report, with its excellent photothermal effect, the combination of Au nanostructures and drug delivery carriers can activate the controllable drug release and realize PTT and chemotherapy (CHT) in one nanoplatform [26]. Thus, Au nanomaterials show a broad prospect in the field of cancer treatment.…”
