In this study, cobalt titanate nanoparticles (CoTiO₃ NPs) were synthesized and applied as a photocatalyst to degrade atrazine. Scanning electron microscopic (SEM) analysis showed irregularly shaped particles prone agglomeration, while X-ray diffraction (XRD) confirmed the formation of rhombohedral CoTiO₃ phase with crystallite size 3.76 nm. Raman spectroscopic vibrations typical for Ti–O Co–O bonds well-defined structure. Thermogravimetric (TGA) that remained stable up 800 °C. The photocatalytic activity NPs was tested under sunlight irradiation results obtained demonstrated excellent efficiency compared photolysis reaction. influenced by concentration (20–50 ppm), catalyst dosage (0.5–2.0 mg/L), pH (4.21–10.22), time (0–120 min). exhibited surface area 32.5 m2/g (DFT) 828.03 m⁻1 (BET), pore volume 0.03925 m3/g, bandgap energy 2.66 eV. Kinetic studies degradation followed Langmuir–Hinshelwood model, reaction being rate-determining step. Adsorption rate constants found range from 0.03828 0.166528 min⁻1, ranged 0.373692 0.977135 min⁻1. also recyclability, maintaining high after five cycles. Scavenger experiments hydroxyl radicals (HO•) are responsible atrazine GCMS complete mineralization carbon dioxide (CO₂) water (H₂O) final products.

Pesticide residues and heavy metals, originating from diverse sources such as agricultural practices industrial activities, pose substantial risks to human health the ecological environment. For instance, of organophosphorus pesticides may damage nervous system, while metals mercury cadmium accumulate in living organisms, potentially leading severe organ damage. The contamination rice with these pollutants has become a critical concern, necessitating development innovative detection techniques that are sensitive, accurate, rapid, portable, intelligent. This review offers an in-depth analysis types, sources, risks, impacts pesticide rice, providing comprehensive understanding challenges solutions associated contaminants. It further provides fundamental principles, comparative advantages, technical constraints both conventional emerging methodologies. These encompass traditional analytical spectroscopy chromatography, well-established immunoassay systems, well biosensing technologies. discussion is substantiated representative case studies demonstrating their practical applications quality assessment safety testing. In addition, this envisions future directions for technologies, emphasizing importance miniaturization, multiplexed detection, integration nanotechnology, real-time monitoring systems. By theoretical foundation advancing food innovation, aims contribute ongoing efforts ensure safety, protect public health, preserve balance.

Abstract 20 years ago it was difficult to imagine the use of nucleic acids in plant protection as insecticides, but today is a reality. At very beginning, new technologies often work inefficiently and are expensive; process their development, qualitative changes occur that make accessible flawlessly. Invented 2008, oligonucleotide insecticides based on CUAD (contact unmodified antisense DNA) platform have been improved possess characteristics amaze imagination: low carbon footprint, high safety for non-target organisms, rapid biodegradability ecosystems, avoidance target-site resistance. This next generation class creates opportunities develop which well-tailored particular population insect pest. biotechnology combines achievements molecular genetics, bioinformatics, vitro acid synthesis providing simple flexible protection. Aphids, one key pests important agricultural crops shape food security, can be controlled by at affordable price already today, ensuring effective control with minimal risks environment. In this article, low-dose concentration (0.1 ng/µL; mg per hectare 200 L water solution) 11-nt long insecticide Schip-11 shows effectiveness aphid Schizolachnus pineti causing 76.06 ± 7.68 mortality rate 12th day (p<0.05). consumption hectare, required amount will about 0.5 USD/ha using liquid-phase DNA makes competitive market. Also we show non-canonical base pairing G:T (T:G) between target pre-rRNA olinscide well tolerated aphids. Thus, base-pairing should taken into consideration during design olinscides not harm organisms.
