Green Synthesis and Characterization of Hydrozincite Nanoparticles from Wild Passion Fruit

Abstract

Green synthesis of nano particles involves the use of whole plant or parts of plant for the bioreduction of metal ions into their elemental form. Hydrozincite nano particles were synthesized using the wild passion fruit. The fruit has got so many health benefits. The synthesized nano particles were characterized by X-Ray diffraction(XRD), Fourier Transform Infra-Red spectroscopy(FT-IR), UV-Vis absorption spectroscopy(UV), Scanning Electron Microscope(SEM) and Energy Dispersive X-Ray Diffraction(EDX). Using XRD the average particle size was found to be 14.032nm. The functional groups of the prepared sample were identified using FT-IR analysis. From UV the absorption peak was noticed at 302.199 nm which confirms the particle was in nano range. The surface morphology of the synthesized particles was noticied as bread spongy from the SEM analysis. The chemical compounds in the nano particles were identified using EDX analysis. Anti-microbial resistance is one of the greatest challenges to global health. The prepared nano particle shows a good effect for both gram-positive and gram-negative anti-bacterial activity.

Introduction

I. INTRODUCTION

In this growing science world, Nanotechnology has produced a number of nanoparticles. There are numerous ways to produce the nanoparticles such as chemical, hydrothermal, electrochemical, microwave assisted, green synthesis etc. Green synthesis method of producing nano particles has gained a much impact on today’s world due to less toxic chemicals and it has became a friendly method for the synthesization of nanoparticles. Green synthesis or Biosynthetic method employs whole plant or some parts of plant for the production of nanoparticles. This method was emerged as a simple and a best alternative method of  chemical  and physical methods[1]. Metal nanoparticles has incorporated a much interest in medical field. Metal nanoparticles have surface to volume ratio, surface energy, spatial confinement and reduced imperfections. Also metal nanoparticles have their own unique electrical, optical properties, physical, chemical, magnetic, thermal and biological properties.[2]

Nanoparticles depend on many factors such as surface area, shape, size, cyrstallinity, functional groups, release of by-products, concentration and etc. Biological methods are user friendly, cost-effective and solves drawback of the chemical synthesis[2].

Nanoparticles has a wide applications in industrial sectors, in which Zinc carbonate Hydroxide has a major role. It was also used in respirators as it reduces the toxic gases. It was also used as a precursor material for the synthesis of ZnO nanoparticles which has a adverse effect in solar cells, electronics and industrial catalyst[3]. Zinc Carbonate Hydroxide is also termed as Hydrozincite or Zinc Carbonate in basic form.

Hydrozincite nanoparticles were synthesized from Wild Passion fruit, which grows in Ooty, The Nilgiris, Tamil Nadu, India. The plant of Passion fruit is a shrub and it is a climber type, the fruit is in oval shape which is pale yellow in colour. The edible part of the fruit is yellowish orange in color. The fruit is best for controlling diabetics and blood pressure.

II. MATERIALS AND METHODS

A. Collection of Fruit

The fresh fruits of Passion fruit (PF) were collected from the campus of Government Arts College, Ooty, The Nilgiris, Tamil Nadu, India. The collected fruits were peeled off and the edible part was taken. This was done because the edible part of the fruit was used for characterization studies. The edible part of the fruit was taken and shade dried at room temperature. It took 4-5 weeks to get dry completely. Then the dried pulps were made into powder using domestic mixer. The powder was stored in an airtight container and used for further studies. The image of fresh fruit and the powder were given in Fig.1 and Fig.2 respectively.

For Staphylococcus aureus the zone of inhibition was 10mm and for Klebsiella pneumoniae showed the zone of inhibition upto 11mm. The A1 showed the activity 32%, 60%, 51%, 46% respectively and A2 showed their activity as 27%, 48%, 41%, 39% respectively. From the above analysis the overall activity of A1 showed a good activity when compared to A2.

Conclusion

The rapid synthesis of Hydrozincite nano particles using Passion Fruit (PE) extract solution has been demonstrated. Structural and morphological properties of the synthesized nano particles were characterized. The present work proves that the PE fruit extracted solution synthesis is a new useful method for the preparation of Hydrozincite nano particles. This simple, cost-effective, time saving and environmental friendly synthetic method gives a potential avenue for various applications. The eco-friendly green approach for the synthesis of nano particles will increase their economic and sustainable management.
