Summary: This study presents the growth and optimization of GaN thin films with preferred c-axis (0002) orientation on Si (111) substrate using Laser Molecular Beam Epitaxy technique. The nitrogen gas flow during film deposition was optimized to enhance the optical efficiency of the GaN thin films. The structural, morphological, and optical properties of the films were analyzed using XRD, AFM, PL, and FTIR spectroscopy. The refractive index of the films decreased with the increase in deposition gas flow, and the refractive index dispersion was analyzed using the SPR technique.

Summary: Silver thin films decorated with carbon nanoparticles were prepared by ablating Ag/C thin film with an Nd: YAG fiber pulsed laser, resulting in a shift of Surface plasmon resonance (SPR) wavelength. Surface enhanced Raman scattering (SERS) was observed in Ag/C samples due to decorating with nano-carbon, showing good stability and high SERS intensity with Rhodamine 6G (Rh 6G) concentration of 10^(-5) mol/L. Simulation results of finite-difference-time-domain (FDTD) confirmed the SERS performance.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: The molecular subtype of breast cancer guides treatment and drug selection. Invasive tests can promote cancer cell metastasis, so the development of high-performance, low-cost diagnostic tools for cancer prognosis is crucial. Liquid biopsy techniques enable noninvasive, real-time, dynamic, multicomponent, quantitative, and long-term observations at the cellular, genetic, and molecular levels. A Cu-Zr metal-organic framework (MOF) nanoenzyme with monatomic Cu attachment has been synthesized and proven to have high catalytic performance. The sensor constructed using this nanoenzyme shows potential for accurate classification of breast cancer serum samples.
