Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

Advanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

Light propagation in nanorod arrays [PDF]

, 2006
We study propagation of TM- and TE-polarized light in two-dimensional arrays of silver nanorods of various diameters in a gelatin background. We calculate the transmittance, reflectance and absorption of arranged and disordered nanorod arrays and compare

Sulfide-Arrested Growth of Gold Nanorods [PDF]

Chemistry of Materials, 2005
The growth of gold nanorods can be arrested at intermediate stages by treatment with Na(2)S, providing greater control over their optical resonances. Nanorods prepared by the seeded reduction of AuCl(4) in aqueous cetyltrimethylammonium bromide solutions in the presence of AgNO(3) typically exhibit a gradual blueshift in longitudinal plasmon resonance,

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

Advanced Functional Materials, EarlyView.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Self-assembly and wetting properties of gold nanorod–CTAB molecules on HOPG

Beilstein Journal of Nanotechnology, 2019
The formation of self-assembled superstructures of cetyltrimethylammonium bromide (CTAB) after drying on a nonwetting highly ordered pyrolytic graphite (HOPG) surface have been investigated using scanning electron microscopy (SEM) and atomic force ...

Optically Responsive Gold Nanorod−Polypeptide Assemblies [PDF]

Langmuir, 2008
Environmentally responsive nanoassemblies based on polypeptides and nanoparticles can have a number of promising biological/biomedical applications. We report the generation of gold nanorod (GNR)-elastin-like polypeptide (ELP) nanoassemblies whose optical response can be manipulated based on exposure to near-infrared (NIR) light.

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

Advanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...
