Plasmonic nano-resonator enhanced one-photon luminescence from single gold nanorods
Strong Stokes and anti-Stokes one-photon luminescence from single gold nanorods is measured in experiments. It is found that the intensity and polarization of the Stokes and anti-Stokes emissions are in strong correlation.

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy
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.

Sulfide-Arrested Growth of Gold Nanorods [PDF]
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
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.
