Fabrication of clinically translatable nanoparticles (NPs) as photothermal therapy (PTT) agents against cancer is becoming increasingly desirable, but still challenging, especially in facile and controllable synthesis of biocompatible NPs with high photothermal efficiency. A new strategy which uses protein as both a template and a sulfur provider is proposed for facile, cost‐effective, and large‐scale...
Design of new nanoagents that intrinsically have both diagnostic imaging and therapeutic capabilities is highly desirable for personalized medicine. In this work, a novel nanotheranostic agent is fabricated based on polydopamine (PDA)‐functionalized Co‐P nanocomposites (Co‐P@PDA) for magnetic resonance imaging (MRI)‐guided combined photothermal therapy and chemotherapy. The ultrahigh relaxivity of...
Mitochondrial‐targeting therapy is an emerging strategy for enhanced cancer treatment. In the present study, a multistage targeting strategy using doxorubicin‐loaded magnetic composite nanoparticles is developed for enhanced efficacy of photothermal and chemical therapy. The nanoparticles with a core–shell–SS–shell architecture are composed of a core of Fe3O4 colloidal nanocrystal clusters, an inner...
Near‐infrared light‐mediated theranostic agents with superior tissue penetration and minimal invasion have captivated researchers in cancer research in the past decade. Herein, a probe sonication‐assisted liquid exfoliation approach for scalable and continual synthesis of colloidal rhenium disulfide nanosheets, which is further explored as theranostic agents for cancer diagnosis and therapy, is reported...
Gold nanoparticle (AuNP) assemblies (GNAs) have attracted attention since enhanced coupling plasmonic resonance (CPR) emerged in the nanogap between coupling AuNPs. For one dimensional GNAs (1D‐GNAs), most CPR from the nanogaps could be easily activated by electromagnetic waves and generate drastically enhanced CPR because the nanogaps between coupling AuNPs are linearly distributed in the 1D‐GNAs...
A thermal “window” of immunogenic cell death (ICD) elicited by nanoparticle‐based photothermal therapy (PTT) in an animal model of neuroblastoma is described. In studies using Prussian blue nanoparticles to administer photothermal therapy (PBNP‐PTT) to established localized tumors in the neuroblastoma model, it is observed that PBNP‐PTT conforms to the “more is better” paradigm, wherein higher doses...
In article number 1801851, Aiguo Wu and co‐workers uncover a series of amino‐functionalized metal–organic frameworks (NH2‐MOFs) as novel and superior templates for porous gold nanoshell deposition (NH2‐MOFs@Aushell) via a facile one‐step method. Platinum nanozymes‐encapsulated NH2‐MOFs@Aushell nanoparticles with a continuous O2‐evolving ability are designed for a combination of photodynamic and photothermal...
AuroShell nanoparticles (sealed gold nanoshell on silica) are the only inorganic materials that are approved for clinical trial for photothermal ablation of solid tumors. Based on that, porous gold nanoshell structures are thus critical for cancer multiple theranostics in the future owing to their inherent cargo‐loading ability. Nevertheless, adjusting the diverse experimental parameters of the reported...
For the first time, topological insulator bismuth selenide nanoparticles (Bi2Se3 NP) are core–shelled with gold (Au@Bi2Se3) i) to represent considerably small‐sized (11 nm) plasmonic nanoparticles, enabling accurate bioimaging in the near‐infrared region; ii) to substantially improve Bi2Se3 biocompatibility, iii) water dispersibility, and iv) surface functionalization capability through straightforward...
Development of nanoagents with strong near‐infrared (NIR) absorbance and high photothermal conversion capacity is highly desired for efficient photoacoustic (PA) imaging and photothermal therapy of cancers. Herein, surfactant‐stripped micelles with photostable near‐infrared dye, β‐thiophene‐fused BF2‐azadipyrromethene (aza‐BDTP), are prepared in the presence of paclitaxel (PTX) with Pluronic F127...
Theranostic materials are of great significance to a personalized precise medicine. However, conventional theranostic agents are mainly fabricated by combining presynthesized independent imaging probes and therapeutic agents, suffering from multiple synthesis procedures, poor morphological control, and time/reagent‐consuming process. Herein, iodinated polypyrrole (I‐PPy) nanoparticles are fabricated...
Multifunctional nanotheranostic agents are of particular importance in the field of precise nanomedicine. However, a critical challenge remains in the rational fabrication of monodisperse multicomponent nanoparticles with enhanced multifunctional characteristics for efficient cancer theranostics. Here, a rational and facile synthesis of monodisperse Gd2O3/Bi2S3 hybrid nanodots (Gd/Bi‐NDs) is demonstrated...
