EDITORIAL

The NBU Journal of Plant Sciences (NBUJPS) started its journey in the year 2007 and has been publishing quality articles in print mode. It is my honour to inform that the Editorial Board has decided to publish the journal in both print and online mode from 2021 (starting Volume 13, March 2021). From now, all the articles of the present and past volumes can be accessed at www.njps.nbu.ac.in. The NBUJPS have officially registered for the membership of CrossRef and now onwards all the articles will be assigned unique DOI numbers and will include other CrossRef services like similarity checking and reference linking. It gives me extreme pleasure to inform that the NBUJPS publishes all the articles at free of charge and will continue to do so in the future also.

    Zinc Oxide Nanoparticles: Different synthesis approaches and applications
    (University of North Bengal, 2021-03) Kundu, Sudipta; Haydar, Md. Salman; Mandal, Palash
    Nanotechnology deals with the synthesis and usage of materials with nanoscale dimension (1-100 nm). Nanoscale dimensions of the particles provide large surface to volume ratio and thus very specific properties. Synthesis of zinc oxide nanoparticles (ZnO NPs) has gained prime importance in recent arena due to its high excitation binding energy and large bandwidth and it has potential applications like anti-diabetic, antibacterial, anti-inflammatory, antifungal, wound healing, antioxidant and optical properties. Zinc (Zn) is a common mineral element in nature which plays an immense role in many biological processes. It is defined as an essential trace element or micronutrient which is very much crucial for the normal growth and the development of all higher plants as well as animals. Zinc directly involves in enzyme function associated with the photosynthesis and energy process in plants. It also plays an important role in maintenance of membrane integrity, formation and production of growth hormone, insulin, thyroid etc. Due to the involvement of large rate of toxic chemicals and requirement of extreme environment, chemical and physical methods of nanoparticle synthesis often became inappropriate. Whereas, green methods are used in a wide range of biological samples including plants, fungus, bacteria, and algae, which act as both reducing and capping agent. Biologically synthesized zinc nanoparticles have been reported for versatile applications in the field of medicine and pharmacy, for bio-imaging and bio-sensor production, in gene therapy and drug delivery system. Zinc nanoparticles also play vital role in agricultural sector including plant growth and development, enhancement of crop yield and post-harvest processing. In spite of being great potential of ZnO NPs for abiotic and biotic stress management, research works in this field is considerably less. This review described the summary of the recent works in the synthesis mechanism, characterization techniques, and applications of biosynthesized ZnO NPs in medicine and agriculture with special reference to application on plant growth, development and abiotic stress management.
