Photo-excitation of plasmons in nano-systems initially results highly localized heating, but the final temperature distribution irradiated nanostructures is almost uniform because heat diffusion equilibrates overall within ∼10−12 s. Here, we show that irradiation with femtosecond pulses enables visualization location plasmonic heating thermal effects such as plasmon-induced melting are frozen at initial energy deposition. Simulations related to orientation laser polarization and geometry...
An ultrasensitive Ag-deposited TiO2 flower-like nanomaterial (FLNM) surface-enhanced Raman scattering (SERS)-active substrate is synthesized via a hydrothermal method, and Ag nanoparticles (NPs) are deposited through electron beam evaporation. Malachite green (MG), which widely used in aquaculture, employed to assess the (SERS) properties of TiO2/Ag FLNMs. They exhibit ultrasensitivity (limit detection (LOD) MG reaches 4.47 × 10-16 M) high reproducibility (relative standard deviations (RSDs)...
A smart drug delivery system with non-destructive surface-enhanced Raman scattering tracing tags and targeted cancer-cell cytotoxicities is constructed.
The effect of a hydrogen bond on the photochemical synthesis silver nanoparticles has been investigated via experimental and theoretical methods. In benzophenone system, process includes two steps, which are that abstraction reaction following reduction reaction. We found for first step, an intermolecular enhances proton transfer. efficiency increases with strength. For second hydrogen-bonded ketyl radical complex shows higher reducibility than radical. inductively coupled plasma-optical...
Since the nanotoxicity of gene delivery carriers has raised world-wide concerns, it is important to trace their intracellular performance, for example via uptake visualization. Here, we develop a novel ultrathin graphitic carbon nitride (g-C3N4) composite nanosystem label-free Raman-traceable small interfering RNA (siRNA) delivery. Through low molecular weight polyethylenimine (PEI) modifications, these nanosystems can obtain siRNA loading capabilities. The lateral size PEI-g-C3N4 around...
In this paper, we describe thymine-protected gold nanoparticles. Assembly of nanoparticles into interconnected network was observed by gradual addition Hg2+. Moreover, the plasmon absorption intensity varied almost linearly with concentration Hg2+, indicating that are potentially useful for signaling It is interesting to note disassembly occurred when Hg2+ in solution high. proposed assembly due coordination thymine groups adjacent nanoparticles, while attributed electrostatic repulsion...
On page 5979, L. Liu, Y. N. Zhou, and co-workers report on the use of highly localized, femtosecond-laser-induced plasmons for modifying metal-oxide nanowire junctions memristor devices. Selective modification units results in an engineered electrical interface with minimal damage to bridged nanowires. This scalable flexible methods shows promise developing multilevel memory applications.
With a slight modification of typical seed-mediated synthesis gold nanoparticles (GNPs), wide range aspect ratios for nanorods, spherical and dumbbell-like GNPs were synthesized. Their unique optical properties such as localized surface plasmon resonance related to the distinct morphologies investigated. On basis preparation condition short nanorods (GNRs), by varying amounts ascorbic acid, morphological transition from rod dumbbell occurred growth mechanism was proposed. Compared with...
