Pesticides are widely used to prevent bug infestation in agricultural crops and to get rid of other pests and disease-carrying creatures including mice, rats, ticks, and mosquitoes from various environment and h In response to this environmental and human health hazard, a dire need for remediation has emerged in the last few decades. Green approaches for the remediation of pesticides can boost sustainable development. A biomimetic approach for degradation of pesticides can have high potential to generate ripples of positive outcomes. Biomimetic catalysts are synthetic chemical molecules which have been inspired by natural processes to mimic their structural and functional properties. This short review concisely focuses on the synthesis of various biomimetic catalysts including metal-based materials, carbon-based materials and others. In this context, recent advances achieved by such biomimetic catalysts for the degradation of pesticides have been covered. It highlights the importance of adopting a biomimetic approach as it provides a green and efficient method for pesticides degradation

As a typical antibiotic pollutant, tetracycline (TC) is producing increasing threats to the ecosystem and human health, and exploring convenient means for monitoring of TC is needed. Here, we proposed alkali-etched imprinted Mn-based Prussian blue analogues featuring superior oxidase-mimetic activity and precise recognition for the colorimetric sensing of TC. Simply etching Mn-based Prussian blue analogues (Mn-PBAs) with NaOH could expose the sites and surfaces to significantly improve their catalytic activity. Density functional theory calculations were employed to screen the molecularly imprinted polymer (MIP) layer for target identification. Consequently, the designed Mn-PBANaOH@MIP possessed the rich channels for substrates to get in touch with the active Mn-PBANaOH core, showing an excellent catalytic capacity to trigger the chromogenic oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) without the use of H2O2. If TC was introduced, it would be recognized selectively by the MIP shell and masked the channels for TMB access, resulting in the obstruction of the chromogenic reaction. According to this mechanism, selective optical detection of TC was achieved, and performance stability, reusability, and reliability as well as practicability were also verified, promising potential for TC monitoring in complex matrices. Our work not only presents an effective way to enhance the enzyme-like activity of Prussian blue analogues but also provides a facile approach for TC sensing. Additionally, the work will inspire the exploration of molecularly imprinted nanozymes for various applications.

“…[17][18][19] Yan et al 2007 synthesized Fe 3 O 4 nanoparticles with intrinsic enzyme-like activity similar to natural peroxidase. 20 Since there has been a sharp increase in research interest in this area, and numerous multifunctional nanozymes 21 and carbon-based nanomaterials, 22 have been reported in the literature as peroxidase enzyme mimics. However, the majority of the recently investigated nanozymes lack substrate specificity, which seems to be the largest barrier preventing their advanced application.…”
