Polymer nanocomposites is a combination of polymer matrix and with a wide range of 1-D, 2-D or 3-D filler materials (organic and inorganic) having at least one dimension in nm range. Polymer nanocomposites have unique structures, morphology as well as mechanical, thermal and electrical properties. Therefore, study on polymer nanocomposites are being continued for about 25 years. The transition from micro- to nano- particles lead to change in its physical as well as chemical properties. Carbonaceous nano fillers such as graphene, CNTs play a very promising role due to their better structural and functional properties such as high aspect ratio, high mechanical strength, high electrical properties etc. Several researchers have been able to successfully implement graphene or hybrid filler based polymer nanocomposites in electrochemical applications, lithium ion batteries, sensors, solar cell, water purification, supercapacitors, drug delivery and tissue engineering. Nanotechnology has the potential to create many new materials and devices with wide-ranging applications, such as in medicine, electronics, and energy production.

To review the utilization of agro-waste in the eco-friendly synthesis of
nanoparticles and their biomedical, catalytic and industrial applications.
Study Design: A review.
Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary.
Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ threats in science and technology. Waste/agro-waste being one out of many threats affecting the eco system has triggered the attention of great minds to exploit fresh avenues in the area of nanotechnology/nanobiotechnology and as a result turning agro waste into readily available raw materials for eco-friendly synthesis of nanoparticles capable of biomedical and industrial properties.
Results: This review has provided information on the advancement of nanotechnology and areas where agro waste have played pivotal roles in the synthesis of eco-friendly nanoparticles. With relevant literature, journals and citations, this review has provided wealth of information on what could be done with agro waste within the confines of nanobiotechnology and beyond.
Conclusion: The advancement of science in the area of nanotechnology/nanobiotechnology has given birth to many innovations the world would have decried as useless centuries back, and now the world is a better place, all thanks to nanotechnology as agro wastes are no longer threats to the eco system.
