“…Upon 808 nm NIR laser irradiation at a power density of 0.25 W/cm 2 , the temperature of bGNR@MSN solution (0.5 mg/mL) exceeded 45 °C within 10 min, while the temperature of MSNs solution with a higher concentration (3 mg/mL) and water only increased to 28.5 °C and 26.8 °C, respectively. The photothermal conversion efficiency of bGNR@MSN was calculated following Roper’s report[40, 41] to be 29.6% (See the Supporting Information for the detailed calculations).…”

Mesoporous silica nanoshell (MSN) coating has been demonstrated as a versatile surface modification strategy for various kinds of inorganic functional nanoparticles, such as gold nanorods (GNRs), to achieve not only improved nanoparticle stability but also concomitant drug loading capability. However, limited drug loading capacity and low tumor accumulation rate in vivo are two major challenges for the biomedical applications of MSN-coated GNRs (GNR@MSN). In this study, by coating uniformly sized GNRs with MSN in an oil-water biphase reaction system, we have successfully synthesized a new bacteria-like GNR@MSN (i.e., bGNR@MSN) with a significantly enlarged pore size (4-8 nm) and surface area (470 m/g). After PEGylation and highly efficient loading of doxorubicin (DOX, 40.9%, w/w), bGNR@MSN were used for positron emission tomography (PET, via facile and chelator-free Zr-labeling) and photoacoustic imaging-guided chemo-photothermal cancer therapy in vivo. PET imaging showed thatZr-labeled bGNR@MSN(DOX)-PEG can passively target to the 4T1 murine breast cancer-bearing mice with high efficiency (∼10 %ID/g), based on enhanced permeability and retention effect. Significantly enhanced chemo-photothermal combination therapy was also achieved due to excellent photothermal effect and near-infrared-light-triggered drug release by bGNR@MSN(DOX)-PEG at the tumor site. The promising results indicate great potential of bGNR@MSN-PEG nanoplatforms for future cancer diagnosis and therapy.

“…In this review, discussion is provided on recent developments in the synthesis of noble metal NPs consisting of the more uncommon Re, Ir, Os, and Rh systems in all forms including metallic, mixed metallic, oxide, and complex molecular forms, that have generally attracted less attention research-wise when prepared by the microemulsion technique. These NPs have different practical uses from biological benefits (e.g., in imaging and cancer therapy) [58,59,60,61], to mainly catalytic and electrocatalytic applications (e.g., hydrogenation of arenes, oxygen reduction in fuel cells, and cyclic acetals synthesis as fuel additives) [62,63,64,65,66]. Interestingly, to our knowledge, there are no previously reported studies for the synthesis of metallic Os NPs by microemulsion methods at the time of writing.…”

This review focuses on the recent advances in the lesser-studied microemulsion synthesis methodologies of the following noble metal colloid systems (i.e., Os, Re, Ir, and Rh) using either a normal or reverse micelle templating system. The aim is to demonstrate the utility and potential of using this microemulsion-based approach to synthesize these noble metal nanoparticle systems. Firstly, some fundamentals and important factors of the microemulsion synthesis methodology are introduced. Afterward, a review of the investigations on the microemulsion syntheses of Os, Re, Ir, and Rh nanoparticle (NP) systems (in all forms, viz., metallic, oxide, mixed-metal, and discrete molecular complexes) is presented for work published in the last ten years. The chosen noble metals are traditionally very reactive in nanosized dimensions and have a strong tendency to aggregate when prepared via other methods. Also, the particle size and particle size distribution of these colloids can have a significant impact on their catalytic performance. It is shown that the microemulsion approach has the capability to better stabilize these metal colloids and can control the size of the synthesized NPs. This generally leads to smaller particles and higher catalytic activity when they are tested in applications.

Medical diagnosis relies on imaging modalities to reveal abnormalities in organs or existence of tumorous lesion. Application of contrast agents alongside imaging techniques is essential in order to obtain high contrast images with distinguishable features. Contrast agents delivered and accumulated in target sites can enhance local signal generation and solve the inherent lack of contrast in imaging techniques. As such, various contrast agents are developed for modalities like computed tomography (CT), magnetic resonance imaging (MRI), and photoacoustic imaging (PAI). For many of these techniques, metal-based agents possess the desired properties for signal and contrast enhancement. Metal oxide nanomaterials present a simple platform for metalbased contrast agents with tunable structure, magnetic and optical properties, surface chemistry, and pharmacokinetics. These can be controlled through synthesis, redox reactions, and surface modification to produce desirable nanoparticles. In this review, recent advances in the development of metal oxide imaging agents are highlighted. Various metal oxide species are discussed, including iron oxides, gadolinium oxides, manganese oxides, tungsten oxides and bronzes, molybdenum oxides, and other oxides of titanium, tantalum, etc. Imaging capability and performance of these metal oxides are presented, and novel functionalization strategies are presented. Finally, recommendations for future research in this area are proposed.
