Summary: Gold-based plasmonic nanocrystals, specifically gold nanobipyramids with (111) plane, showed higher photothermal performance compared to gold nanorods with (200) plane in noninvasive photothermal therapy, as demonstrated by experimental studies and density function theory (DFT) simulations. Water desorption energy on the Au(111) surface was found to be lower than on the Au(100) surface, indicating easier desorption for photothermal heating. Additionally, AuNBPs with (111) plane exhibited higher efficiency in photothermal therapy against Escherichia coli (E. coli) under near-infrared (NIR) laser irradiation compared to AuNRs.

Summary: Periodic arrangements of plasmonic nanoparticles in supercrystals exhibit strong light-matter interaction. This study analyzes experimental data to investigate the reproducibility and tunability of gap sizes in relation to the particle diameter and molecular weight of stabilizing ligands. Different behaviors of polystyrene-based ligands are observed depending on their molecular weight, leading to important consequences for the correlation between nanoparticle diameter and resulting gaps in supercrystals. An alternative volume-based approach is proposed for predicting gap sizes in larger nanoparticles, which provides robust guidelines for achieving gaps below 5 nm for enhanced light-matter coupling.

Summary: This study investigates the surface chemistry of gold nanoparticles using gel electrophoresis. It is found that coadsorption of PEG ligands significantly reduces protein adsorption and matrix effects of cell media, improving the colloidal stability of nanoparticles.

Summary: We present a microscopic approach to understand the beginning of radial oscillation in silver nanoparticles. Using the Heisenberg equation of motion framework, we demonstrate that the coupled dynamics of coherent electron occupation and coherent phonon amplitude induce periodic size oscillations in the nanoparticle. Our results suggest a more direct coupling mechanism between field intensity and coherent phonons, which triggers size oscillations via optically induced electron density gradient. This mechanism is more efficient than the incoherent heating process commonly discussed in literature and provides a better explanation for the early onset of oscillations observed in recent experiments.

Summary: Currently, the dynamics of optically excited plasmonic nanoparticles are explained as a series of scattering events caused by nanoparticle breathing oscillations initiated by statistical heat transfer from thermalized electrons to the lattice. However, a phase mismatch between theory and experiments suggests an additional excitation mechanism. Through optical transient absorption spectroscopy and time-resolved single-particle X-ray diffractive imaging, we found that optically induced electron density gradients are the initial driving source for breathing oscillation and confirmed the need for an additional excitation mechanism for thermal expansion. Our new model reproduces all experimental observations.

Summary: Optical-pump-terahertz-probe (OPTP) experiments are commonly used to study the behaviors of excited carriers in semiconductors. However, the size difference between the probe beam and the pump beam can cause distortions in the sample response and uncertainties in calculated conductivities and models. By investigating the influence of pump beam spot size and evaluating model calculations, we show the impact of this effect on the acquired data and provide guidelines for optimal experimental configurations.
