Sitophilus zeamais is a highly destructive pest of stored grains worldwide. To develop novel RNA insecticides, the double-stranded S. cytochrome c oxidase (dsSzCOXs: dsSzCOXI, dsSzCOXII, and dsSzCOXIII) was successfully expressed in pET28a-BL21(DE3)-RNaseIII- system remarkably downregulated expression level SzCOXs through injection or feeding methods, leading to high mortalities both larvae adults. Under their optimal conditions (isopropyl β-d-thiogalactoside, 0.6 mM), yields dsSzCOXI (at 28 °C for 4 h), dsSzCOXII 37 6 dsSzCOXIII h) were 8.49, 5.80, 6.04 μg/mL respectively. The chitosan-based gene delivery composed dsSzCOXs (CS@dsSzCOXs) established insecticidal effect adults via mixing wheat seeds, with mortality reaching 50% on day ten. Consequently, this nanoparticle-mediated expected be an effective approach control.

Abstract A mixed‐ligand‐based novel 3D Cd(II)‐based metal‐organic framework (MOF) is devised from π‐electron‐rich organic struts that shows two‐fold interpenetrated bilayer‐pillar structure. The strong luminescence of the MOF gets remarkably quenched by roxarsone (ROX) organo‐arsenic in water. material further exemplifies one‐of‐a‐kind fluoro‐switchable probe for antibiotics and exhibits massive turn‐off emission tetracycline (TTC), whereas sulfamethazine (SMZ) triggers an unprecedented 120% enhancement. Apart regenerative, fast‐responsive, selective fluoro‐detection all three feed‐additives, particularly significant nanomolar limits detection (LOD) ROX (48.9 n m ), LOD SMZ (33.9 ) ranks lowest, TTC (22.8 stands second lowest among reported sensory MOFs. Besides varying degrees energy transfer contribution TTC, density functional theory calculations manifest changes levels individual organo‐aromatics additionally describe framework–analyte supramolecular interactions. sensor works equally well different wastewater specimens a wide pH range with good recovery percentage. To broaden practical scope material, cheap MOF@paper strip as reconfigurable MOF@chitosan@paper bio‐composite developed successfully employed instantaneous monitoring both at their low concentrations.

A new triazine containing pyridinium organic polymer (TB-Py-COP) based on 4-amino-1,8-naphthalimide Tröger's base is developed and employed as a fluorescent chemosensor for selective sensing of organoarsenic feed additives in water. TB-Py-COP was readily synthesized by reacting "V-shaped" bis-[N-(4-pyridyl)methyl)]-9,18-methano-1,8-naphthalimide-[b,f][1,5]diazocine with cyanuric chloride DMF at 100 °C 3 days. exhibited strong fluorescence emission water displayed selective, reversible responses the roxarsone additive nanomolar (19 nM) level sensitivity. The Stern-Volmer quenching constant (K SV) determined to be 1.4 × 104 M-1. further demonstrated competitive environments, lake water, buffer solutions.
