Effects of Copper Nanoparticles (CuO NPs) on Crop Plants: a Mini Review

Nanoparticles (NPs) received great attention due to their unique properties and beneficiary applications in various sectors. The rapid growth of NPs production and its abundant uses create additional risks on an anthropogenically modified ecosystem, and consequently on human beings. The main aim of this review article is to explore the possible threats imposed by CuO NPs on cultivated crop plants. We searched PubMed, Google Scholar, and Web of Science portals for the literature review to get latest updated information and developments in the field of toxicity of CuO NPs on cultivated plants. This review article clearly denoted the toxic effects of CuO NPs on cultivated crop plants by inhibiting seed germination, decreases in the shoot and root lengths, reduction in photosynthesis and respiration rate, and morphological as well enzymatic changes. The information is significant to researchers and policymakers to define limits and future prospectives.
