Summary: This article presents a new method for dopamine detection using ultrastable gold nanoparticles, modified with a dopamine-binding aptamer, to achieve sensitive and selective detection of different concentrations of dopamine without inducing nanoparticle aggregation. The method shows good linearity between dopamine concentration and nanoparticle plasmon shift, with the ability to filter out interfering molecules and permit nanoparticle reuse.

Summary: Electrogenerated chemiluminescence (ECL) microscopy is a promising technique for mapping chemical reactions on single nanoparticles. By coupling ECL dyes with plasmonic nanoparticles, such as hexagonal arrays of gold nanodisks, signal intensity can be significantly improved. Varying the lattice spacing of these nanoparticles can result in a 23-fold enhancement of ECL intensity due to increased dye-array near-field coupling.

Summary: Gold nanobipyramids have been studied for their electric field intensity distribution under different conditions, such as aspect ratio and sharpness. Changes in these parameters can lead to red plasmon shift of extinction and enhancement of extinction peak. Moreover, incident polarization angle can affect the distribution of electric field intensity at the tips.

Summary: Strain engineering is shown to be an effective method for tailoring the electronic and optoelectronic properties of semiconductor nanomaterials and nanodevices, leading to novel functionalities. Experimental evidence demonstrates that the conductivity and hole mobility of gallium arsenide nanowires vary with different levels of uniaxial tensile stress, attributed to changes in valence band structure caused by stress and strain. Furthermore, lattice strain in the nanowires is quantified and a significant red shift of the band gap induced by stress and strain is observed.

Summary: Copper sulphide (covellite) nanoplatelets have emerged as a plasmonic platform in the near-infrared with ultrafast nonlinear optical properties. The free-carrier density in CuS can be further tuned by chemical doping, using ion exchange to replace Cu with increasing content of Zn in the nanoparticles. This approach provides new opportunities for tuning the plasmonic response of covellite nanocrystals and the carrier relaxation time.

Summary: This study demonstrated the possibility for thermally-controlled tuning of the localized surface plasmon resonance (LSPR) band position of gold nanoparticles in specific gold-doped glasses, achieving a maximum red-shift of up to 100 nm. The distinct red-shift of the LSPR band, driven by phase separation, represents a new approach for precise plasmonic tuning of gold nanoparticles in glass.

Summary: In this study, the post-synthetic shape tailoring/modification of Au nanostars was achieved by breaking the coordination bonds between PVP and metal using NaBr and Br2. This process selectively etched specific crystal facets from the nanostar spikes and redeposited them at the core, leading to quasi-spherical dimensions over time. The addition of AgNO3 at any point allowed careful modulation of the intermediate morphologies, enabling a refined exploration of the wide range of plasmonic applications.

Summary: In this paper, a Metal-Dielectric-Metal (MDM) type nanocavity structure is proposed, which utilizes silver nanorings as the top layer, UCNPs as the dielectric layer, and silver mirrors as the bottom layer. Efficient absorption peaks are generated at wavelengths of 808 nm, 980 nm, and 1530 nm, producing strong local fields for excitation light. Numerical simulations yield fluorescence enhancement factors of approximately 7.03 x 105, 3.02 x 105, and 6.18 x 104 at wavelengths of 808 nm, 980 nm, and 1530 nm, respectively. This design offers a new way to enhance the efficiency of up-conversion luminescence and improves the performance of applications such as biosensors and filters.

Summary: Actuators based on hydrogels are promising for biomimetic soft robots. However, their actuation process lacks perceptual capacity. This study proposes a fast photo-thermal responsive and self-sensory soft actuator based on a sponge-like hydrogel, demonstrating ultrafast response and self-sensing capabilities. Inspired by neuromuscular systems, a smart self-adaptive actuator is designed, enabling active perception and shape transformation. This sensory actuating hydrogel contributes to the development of artificial intelligent soft robotics with higher autonomy and complexity.

Summary: Accurate identification of tumor margins during cancer surgeries is essential, and a high-throughput detection technique is needed. The conventional histopathological analysis of frozen tissue sections often shows variability, especially in areas without trained pathologists. This study introduces a high-throughput three-dimensional histological electrophoresis device that utilizes tumor-specific proteins to identify and contour tumor margins intraoperatively. Testing on xenograft models and human cervical cancer models demonstrated the effectiveness of this approach. The device is expected to improve the accuracy and efficiency of diagnosing various cancers.
