Pesticide usage has increased to fulfil agricultural demand. Pesticides such as organophosphorus pesticides (OPPs) are ubiquitous in world food production. Their widespread unavoidable detrimental consequences for humans, wildlife, water, and soil environments. Hence, the development of more convenient efficient pesticide residue (PR) detection methods is paramount importance. Visual detecting approaches have acquired a lot interest among different sensing systems due inherent advantages terms simplicity, speed, sensitivity, eco-friendliness. Furthermore, various detections been proven enable real-life PR surveillance environment water. Fluorometric (FL), colourimetric (CL), enzyme-inhibition (EI) techniques emerged viable options. These technologies do not need complex operating processes or specialist equipment, simple colour change allows visual monitoring result. on-site water environments discussed this paper. This paper further reviews prior research on integration CL, FL, EI-based with nanoparticles (NPs), quantum dots (QDs), metal-organic frameworks (MOFs). Smartphone PRs also reviewed. Finally, conventional nanoparticle (NPs) based strategies compared.

Chemo-dynamic therapy (CDT) based on the Fenton or Fenton-like reaction has emerged as a promising approach for cancer treatment. However, autophagy-mediated self-protection mechanisms of cells pose significant challenge to efficacy CDT. Herein, we developed metal-DNA nanocomplexes (DACs-Mn) enhance CDT via DNAzyme inhibition autophagy. Specifically, Mn-based catalyst in DACs-Mn was used generate highly hydroxyl radicals (⋅OH) that kill cells, while ATG5 incorporated into inhibited expression autophagy-associated proteins, thereby improving By disrupting self-protective pathway under severe oxidative stress, this novel found synergistically both vitro and vivo models, effectively amplifying tumor-specific damage. Notably, Metal-DNA can also induce immunogenic cell death (ICD), inhibiting tumor metastasis. bilateral model mice, combined autophagy followed by immune checkpoint blockade shown potential effective treatment modality primary metastatic tumors.
