Summary: We developed a simple and low-cost assay utilizing mesoporous silica nanoparticles for detecting analytes. Palladium nanoparticles covered with mesoporous silica (Pd@mSiO(2)) were used, and specific proteins or DNA were capped onto the nanoparticles to prevent catalyzation. When target antigens or complementary DNA sequences were present, the cap dissociated, allowing the conversion of non-fluorescent molecules to fluorescent molecules. The assay showed a wide detection range and has the potential for point of care diagnostics in low-resource settings.

Summary: The impact of surface functionalization on mesoporous silica nanoparticle (MSN) carriers and the release of Fenofibrate (FNB) was investigated. The MSNs were modified with either (3-aminopropyl) triethoxysilane (APTES) or trimethoxy(phenyl)silane (TMPS), and the density of the functional groups was measured. The FNB loaded in the MSNs with ordered cylindrical pores showed amorphization, and the glass transition temperature slightly changed depending on the surface modification. Dielectric studies revealed multiple relaxations associated with different FNB populations and correlated their mobility with drug release profiles.

Summary: In this study, diphenylcarbazide functionalized mesoporous silica (DPC-SBA-15) was successfully synthesized for selective removal of chromium (Cr(VI)) from aqueous solution. Characterization techniques such as small-angle XRD, SEM, HR-TEM, FTIR, and CHNS elemental analysis were used to investigate the structural characteristics and surface modification of DPC-SBA-15. The results showed that DPC-SBA-15 exhibited excellent adsorption performance for Cr(VI) ions under optimized conditions, with fast initial kinetics and a high removal efficiency.

Summary: The selective removal of Pb(II) ions was achieved by modifying mesoporous silica materials, SBA-NS and SBA-ENS, which showed improved adsorption performance and selectivity for Pb(II) in binary metal ion systems. The experimental results indicated that the imine N atoms on the two adsorbents played a dominant role during the Pb(II) sorption process, providing a potential solution for waste water treatment and lead recycling.

Summary: This paper reports the recognition and selective interfacial enrichment of nonpolar versus polar gases for spectroscopic mid-infrared on-chip sensing through the use of silane monolayers of different polarities. The study introduces high-surface-area nanocoatings and strategically selected silanes for surface modification, allowing control of preferential adsorption and concentration of polar versus nonpolar gas analytes. The developed interfacial assemblies enable diverse spectroscopic gas sensing platforms for applications in health diagnostics, environmental monitoring, and process control.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
