Green chemistry has been an eye catching area of interest since the past few years. With the problem of energy crisis looming high and its constraint being particularly vulnerable on the developing economies, the need for giving alternative traditional chemistry a serious consideration as well as adequate room for development has received significant boost through the coveted efforts of multidisciplinary and interdisciplinary scientific fields. Nanoscience has been the right field in this dimension as it opens up the door to multiple opportunities through enabling a number of chemical, biochemical, and biophysical transformations in a significantly easier and reliable manner. The use of nanoparticles has made the fields of catalysis, synthesis, and enzyme immobilizations as well as molecular interactions a lot much easier, rapid and easily controllable. This review article sheds light on the popular alternative synthesis routes being employed for the synthesis of nanoparticles, the pivotal being from microbes, plants, and chemical routes via sonication, microwaving, and many others.

Biosensing has been one of the hottest topic attracting scientific minds since long back. It is so as biological entities are very complex and are directly associated with the existence of a healthy environment. The design of biosensors also has witnessed significant changes in the recent past. Biosensors for applications as diverse as food quality estimation, environmental monitoring, and diagnosis of clinical and metabolic complications have come to the fore. Nanotechnology has bestowed some highly exciting ingredients for the improvement of sensing phenomenon. The use of diverse nanomaterials ranging from nanoparticles, nanotubes, nanorods, and nanowires has enabled faster detection and its reproducibility in a much better way. The unique properties of nanomaterials such as high electrical conductivity, better shock bearing ability, and the sensitive responses such as piezoelectric and versatile color based detection mechanisms are only the results of congregation of nanomaterial properties. This paper highlights the different types of biosensors based on different types of nanomaterials and their developmental and implicational aspects.

Man is a social animal, hence music also has a special place in the society due to its connection with humans. Man originated with creation as an integral element of creation. This is the reason why a man tied in the periphery of birth and death was born by collecting sanskars from the world itself. He saw with eyes, heard with ears and experienced with the senses and sanskars were formed in him. For this reason, man became a thoughtful creature (zippadahpandpun) and then he became a signifying creature (jansapapamandpun) and due to these two reasons he became a social animal (javapapanspandpuns). मनुष्य एक सामाजिक प्राणी है, इसलिये संगीत भी मनुष्य से जुड़ा होने के कारण समाज में अपना एक विशेष स्थान रखता है। मनुष्य सृष्टि के अंगभूत तत्त्व के रूप में सृष्टि के साथ ही उत्पन्न हुआ। यही कारण है कि जन्म-मरण की परिधि में बँधा मनुष्य सृष्टि से ही संस्कार बटोरकर उत्पन्न हुआ। उसने आँखों से देखा, कानों से सुना तथा इन्द्रियों से अनुभव किया और उसमें संस्कार बन गये। इसी कारण मनुष्य एक चिन्तनशील प्राणी (ज्ीपदापदह ंदपउंस) बना और फिर वाचक प्राणी (ज्ंसांजपअम ंदपउंस) बना और इन्हीं दो कारणों से वह सामाजिक प्राणी (ैवबपंस ।दपउंस) बना।
