Summary: This paper presents a spectrometer-based surface plasmon resonance imaging (SPRi) technique without mechanical scanning. A polarized broadband light source illuminates an object via a gold-coated prism, and the reflected light is spatially modulated by a digital mirror device (DMD) and measured with a spectrometer. Reflectance spectral images are reconstructed using the Hadamard transform (HT), and a refractive index (RI) map is visualized by analyzing the resonance peak shift at each image pixel. The method is demonstrated to have high resolution, sensitivity, and dynamic detection range, with experimental results validating the simulations.

Summary: The 5-year survival rate for pancreatic adenocarcinoma (PA) is less than 10%, but early-stage diagnosis and resection can increase the 4-year survival rate up to 78%. A novel PDGFR beta-targeting peptide (YQGX-10) was designed and coupled with a near-infrared fluorescent dye for precise detection of PA. The probe showed high affinity and specificity and could be used for NIRF-guided tumor resection of PA. A radioactive probe was also constructed for the diagnosis of PA with high specificity and sensitivity.

Summary: This study demonstrated a facile synthesis of Ir/Gd bimetallic oxide nanotheranostics (BSA@Gd2O3/IrO2 NPs) with good biocompatibility using a biomineralization method. BSA@Gd2O3/IrO2 NPs showed high longitudinal relaxivity and X-ray absorption capability, making them suitable for MR and CT dual-modal imaging. Additionally, BSA@Gd2O3/IrO2 NPs acted as efficient photothermal conversion agents and photosensitizers, and could decompose endogenous H2O2 to produce O-2, improving the phototherapeutic effect. This work is important for the development of versatile nanotheranostic systems using mild and robust biomineralization methods.

Summary: Researchers report a new approach called proximity-induced nucleic acid degrader (PINAD) to target and degrade RNA using small molecules. They have designed two families of RNA degraders that target two different RNA structures in SARS-CoV-2: G-quadruplexes and the betacoronaviral pseudoknot. These novel molecules have been shown to degrade their targets in vitro, in cellulo, and in vivo SARS-CoV-2 infection models. PINAD enables the conversion of any RNA binding small molecule into a degrader, potentially expanding the space of druggable targets and diseases by targeting and destroying disease-related RNA species.

Summary: Nanosubstrate engineering can modulate stem cell differentiation in tissue engineering through biomechanical means. The effect of clathrin-mediated processes on this behavior has not been explored. In this study, we developed integrin-binding nanosubstrates with confined nanogeometries to regulate clathrin-mediated signaling pathways for modulating stem fates. Isotropic ligand presentation on the nanoscale enhanced clathrin expression and facilitated uptake of dexamethasone-loaded nanoparticles, promoting osteogenesis. In contrast, anisotropic ligand nanogeometry suppressed clathrin-mediated nanoparticle entry and reinforced mechanotransduced signaling by strengthening the association between clathrin and adhesion spots. Inhibiting focal adhesion formation hindered cell spreading and increased endocytosis efficiency.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
