The sudden absorption of light by a metal nanoparticle launches series relaxation processes (internal thermalization, acoustic vibrations, and cooling) which induce transient modification its optical response. In this work, the response associated with internal thermalization single gold nanodisk (occurring on few picoseconds time scale) was quantitatively investigated time-resolved spectroscop...

OBJECTIVES NanoDisk-amphotericin B (ND-AMB) is a protein-phospholipid bioparticle containing a "super aggregate" form of antifungal AMB. While lipid-based formulations of AMB, including liposomal AMB (L-AMB), are safer than the deoxycholate (DOC) solubilized form (DOC-AMB), the potency of lipid-based formulations is attenuated. We have developed an AMB-based therapy that is both well tolerated ...

We report the experimental demonstration of an optically pumped silver-nanopan plasmonic laser with a subwavelength mode volume of 0.56(lambda/2n)(3). The lasing mode is clearly identified as a whispering-gallery plasmonic mode confined at the bottom of the silver nanopan from measurements of the spectrum, mode image, and polarization state, as well as agreement with numerical simulations. In a...

We proposed an infrared narrowband metamaterial perfect absorber (MPA) which is induced by toroidal dipole resonance in a dielectric-metal hybrid system. The MPA composed of amorphous-silicon (a-Si) nanodisk quadrumer clusters, dielectric spacer, and Au substrate, where the spacer inserted between Si disk substrate. Near field distribution multipole decomposition far-field, scattering powers sh...

As a quasiparticle formed by light and excitons in semiconductors, the exciton polariton (EP) as quantum bus is promising for development of interconnect devices at room temperature. However, significant damping EPs material generally causes loss information. We propose mechanism to overcome destructive effect EP on its mediated correlation dynamics emitters (QEs). Via an investigation near-fie...

Nanometer-scale, apolipoprotein-stabilized phospholipid bilayer disk complexes (nanodisks [ND]) harboring the toxic and poorly soluble antileishmanial agent amphotericin B (AMB) were examined for efficacy in treatment of Leishmania major-infected BALB/c mice (Mus musculus). L. major-infected mice were intraperitoneally (i.p.) treated with AMB-ND in 0-, 1-, and 5-mg/kg doses at 24 h, 48 h, and 4...
