Tetracyclines (TCs) are widely present in the environment with extreme toxicity, low concentrations, coexistence a variety of pollutants, and similarity their individual molecular structures toxicology. These challenges make it difficult to analyze monitor TCs as class molecules simultaneously. In this study, broad-spectrum aptamer capable recognizing was developed by artificially editing single-specific aptamer. Subsequently, based on mathematical proof detection TCs, an electrochemical sensor constructed enable simple rapid monitoring high sensitivity, selectivity, wide range. The exhibits range 0.01 1000 nM limit 1.18 pM, while maintaining excellent selectivity even presence interfering substances at concentrations up 100 times test concentration. This is suitable for quantifying overall level various environmental scenarios, facilitating study transport transformation processes systems. Finally, recognition mechanism elucidated, which makes method rational universal, will help future researchers obtain aptamers analysis multiple classes pollutants.

Abstract From the invention of papermaking in ancient times to wide range modern applications fields textiles, medicine, food, and nanotechnology, development cellulose‐based materials reflects humanity's ongoing exploration utilization renewable resources. The production is highly dependent on solvents which can deconstruct regenerate structure cellulose. However, solubility, processing technology, application cellulose based deconstruction regeneration require further research breakthroughs. Here, structural characteristics, solvent system, modification methods, degradation performance are briefly introduced. Moreover, life cycle assessment discussed improve evaluation system demonstrate environmental friendliness potential materials. Finally, several key technologies strategies that assist meeting requirements bioplastics emphasized, with a view increasing recognition their advantages as biodegradable
