Summary: In this study, we developed an air-water interface mediated co-assembly strategy to prepare flexible 2D superlattices of Au octahedra with tunable orientations. The self-assembly of Au octahedra into different orientations (face-up, edge-up, and vertex-up) was controlled by the surface wettability of the nanoparticles. The SERS performance of the 2D superlattices was studied, and the vertex-up orientation showed the highest enhancement performance and uniformity.

Summary: We report the detection of plasmon-enhanced Raman scattering (PERS) in self-assembled AgxC60 nanocomposite films and investigate the evolution of this effect with increasing Ag concentration, x, in the range of 2 < x < 25. The PERS effect is found to be closely related to the dipolar plasmonic mode generated by uniform 3D-ensemble of Ag nanoparticles in the C-60-based matrix. The analysis of absorption spectra reveals strong coupling between the dipolar plasmon mode and the C-60 low-energy exciton, indicating energy exchange between high- and low-energy polaritonic states. The obtained PERS spectra show sensitivity of the C-60 vibrational modes to the plasmonic field strength, which can be tuned by adjusting the Ag concentration.

Summary: In this study, a two-step procedure for preparing biohybrid nanoparticles with a hydrophobic quantum dot core and a multilayer coating of human serum albumin is reported. These nanoparticles, decorated with proteins like human serum albumin or human transferrin, retained their fluorescent properties and showed no corona effect in the presence of serum. They were selectively taken up by lung cancer and neuroblastoma cells but not by non-cancerous cells or differentiated neurons. Moreover, digitoxin-loaded transferrin-decorated nanoparticles specifically reduced the number of lung cancer cells. Finally, the in vivo uptake of these biohybrid nanoparticles by retinal cells in mice demonstrated their excellent targeting and traceability.

Summary: A flexible and easily processable polymer composite is developed from naturally occurring piezoelectric materials for efficient energy-harvesting applications. The induced electroactive phases in tomato peel (TP)-and cotton (CTN)-based poly(vinylidene fluoride) (PVDF) composites have been explored through structural, thermal, and morphological analyses. The CTN-based composite shows higher output voltage and current compared to the TP-based composites due to significant induction of the piezoelectric phase in the presence of suitable electroactive cotton, demonstrating its potential as an efficient and sustainable biomechanical energy harvester.

Summary: In this study, two soluble and highly fluorescent triazine-based conjugated polymer networks (TCPNs) were synthesized by conjugating a thiophene unit with a triazine ring through a phenyl linker. The effect of introducing alkyl and oligoethylene glycol side chains on the TCPNs' solubility, optical properties, conductivity, and biological activities was investigated. Additionally, non-oxidative doping of the TCPNs was achieved through the reaction with a Lewis acid, leading to significant optical switching and conductivity changes. These TCPNs also demonstrated stability and gelation after doping, and exhibited abilities for fluorescence imaging and cancer cell inhibition. This study highlights the potential applications of triazine-based conjugated polymer networks in electronic, optoelectronic, cell imaging, and chemotherapeutic fields.
