Summary: The impact of Cu nanoparticles with distinct plasmonic properties on the Nd3+ near-infrared emission in neodymium and copper co-doped phosphate glass was examined. It was found that the merely plasmonic glass consistently showed quenching of Nd3+ photoluminescence, while the dichroic glass exhibited enhanced near-infrared emission under excitation at 747 and 803 nm. However, the decay times of the Nd3+ 4F3/2 emitting state were similar to the melt-quenched precursor. Scattering effects from Cu nanoparticles are suggested to contribute to the enhancement of photoluminescence.

Summary: The potential of Bi2MoO6 nanoparticles as a photocatalyst for decomposing organic pollutants has been widely explored, but their potential for photodynamic therapy (PDT) has not been investigated. In this study, a novel nanocomposite based on Bi2MoO6/ MoS2/AuNRs was designed to overcome the limitation of UV absorption. The nanocomposite exhibited high photodynamic ability and POD-like activity under NIR-II light irradiation.

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: This study investigates the hyperenhancement effect of Raman scattering (RS) appearing on microcracks of metal deposition (silver and gold) on uniaxially stretched polymer track-etched membranes. The deformation of membranes with high surface density and small pore diameter leads to the development of many microcracks in the metal coating. The efficiency of surface enhancement RS (SERS) is investigated using malachite green as an example, and the ability to recognize extremely low concentrations of the substance is demonstrated. The study finds that the SERS signal increases with the deformation of the samples and shows even greater enhancement after unloading and relaxation. Tensile strain experiments and changes in electrical conductivity confirm the hypothesis that SERS appears on microcrack edges with a relatively small distance between their boundaries. SERS technique is proposed for analyzing the formation of micro- and nanocracks on metal coatings.

Summary: Surface-enhanced Raman spectroscopy (SERS) is a powerful technique for biosensing, but it has limitations in signal strength and concentration changes. The usage of hollow-core microstructured optical fibers (HC-MOFs) and functionalization with gold nanoparticles can improve the sensitivity and limit of detection of SERS. The analysis of spectral shifts in the optical transmission of HC-MOFs provides a quick technique to study the formation of the SERS platform. This research has potential implications for point-of-care medical diagnosis based on liquid biopsy and exhaled air analysis.

Summary: We conducted a comprehensive study on the luminescence characteristics and valence states of Mn impurity ions in a YAl3(BO3)(4):Mn crystal using X-ray fluorescence analysis and XANES spectroscopy. We identified the origins of different luminescence and absorption lines, including those caused by Mn2+ and Mn3+. The crystal-field and Racah parameters for Mn3+ in YAB:Mn were estimated using optical spectroscopy and Tanabe-Sugano diagrams. This study provides valuable insights for further applications, such as luminescent thermometry.

Summary: Proteolytic activity plays a crucial role in cell homeostasis and function, with implications in cancer progression and treatment response. Endosomes, which are often the final destination of internalized nanoparticles, are major sites of cellular proteolytic activity. However, little is known about the impact of nanoparticles on endosomal biology. In this study, we generated albumin nanoparticles with varying resistance to proteolysis and demonstrated a relationship between their sensitivity to proteases and drug delivery properties, irrespective of the degree of proteolytic degradation.

Summary: Non-invasive visualization and monitoring of tissue-engineered structures in a living organism is a challenge. We used upconversion nanoparticles (UCNPs) as photoluminescent nanomarkers in scaffolds to solve this problem. The results showed that the UCNPs' photoluminescent signal decreased gradually in all the examined scaffolds, indicating their biodegradation and release of photoluminescent nanoparticles into the surrounding tissues.

Summary: Frontiers in theranostics are driving the demand for multifunctional nanoagents. Upconversion nanoparticle (UCNP)-based systems activated by near-infrared (NIR) light deeply penetrating biotissue are a powerful tool for the simultaneous diagnosis and therapy of cancer. The intercalation into large polymer micelles of poly(maleic anhydride-alt-1-octadecene) provided the creation of biocompatible UCNPs. The intrinsic properties of UCNPs (core@shell structure NaYF4:Yb3+/Tm3+@NaYF4) embedded in micelles delivered NIR-to-NIR visualization, photothermal therapy, and high drug capacity.

Summary: The latest research emphasizes the advantages of using crystalline media with negative optical anisotropy parameter (OAP) for Faraday devices. These media eliminate the degrading impact of thermal-stress-induced birefringence in high power light operations. The successful growth of OAP-negative fluoride crystals (KDF and NDF) and their material properties have been characterized, demonstrating the transparency at mid-IR wavelengths and sufficient Verdet constant for practical implementation.
