International Journal of Advanced Science and Engineering, 2019
Nanotechnology is nothing but a branch of technology smaller in size, lighter in weight, stronger in strength due to its large surface area to volume ratio. The applications of nanotechnology have been widely used by several industries globally, especially in the development of innovative products using novel materials in cosmetics, paints, ceramic, textile coatings and pharmaceuticals. Nanoparticles have been designed in different morphological structures at the microscopic level such as nanospheres, nanotubes, nanorods, nanowires, nanoplatelets, nanoflower, nanoparticles and nanoneedle. By bearing in mind the importance of Nano dimensional material, the present review article, therefore, focuses on the reviews of the advances and development of nanotechnology applications to cosmetics, paints, textile and medical research.
A Comprehensive Review of Nanomaterials: Types, Synthesis, Characterization, and Applications
Biointerface Research in Applied Chemistry, 2023
Nanotechnology has infiltrated all sectors due to its unique and evident impacts, which give the scientific community numerous breakthroughs in the medical, agricultural, and other domains. Nanomaterials (NMs) have risen to prominence in technological breakthroughs due to their adjustable physical, chemical, and biological characteristics and superior performance over bulk equivalents. NMs are divided into many categories based on size, composition, capping agents, form, and origin. The capacity to forecast NMs' unique features raises the value of each categorization. As the manufacturing of NMs and industrial uses grow, so does their demand. The purpose of this review is to compare synthetic and naturally occurring nanoparticles and nanostructured materials to determine their nanoscale characteristics and to identify particular knowledge gaps related to the environmental application of nanoparticles and nanostructured materials. The paper review includes an overview of NMs' history and classifications and the many nanoparticles and nanostructured materials sources, both natural and manufactured. Furthermore, the many applications for nanoparticles and nanostructured materials.
Innovation in Science and Technology
Nanotechnology is science, technology, and engineering that is directed at the nano scale (1-100 nm). This is a diverse and attractive field, owing to its unique properties and applications. The surface- to- volume ratio is the most important property of a material, which makes a clear difference between bulk materials and materials at nano scale. Nano can be referring to materials, particles, thin films, wires, fibers, etc. Nanotechnology is a revolutionary method for developing of new systems and technologies. In this study, the types of nano materials on their structures are discussed. The remarkable properties of the nanomaterials have also been explained.

Nanoscale materials for engineering and medicine
2008
Materials with nanoscale features have new or improved properties compared to bulk materials. These properties depend on the composition, size, and shape of the material, and include high specific strength and modulus, low melting point, high electrical and thermal conductivity, a large surface area to volume ratio, nearly defect-free structure, magnetic and optical properties, and sensing and actuation properties. This talk will discuss synthesis, processing, and application of nanoscale materials for engineering and medicine. Recent advances in nanoparticle synthesis include development of "Black Cotton" which is centimeter long carbon nanotubes grown in arrays, improved carbon nanofiber material, and development of carbon nanosphere chain material which has the morphology of carbon onions chained together. Applications of these materials under development include spinning Black Cotton into thread to produce a new smart material with reinforcement, sensing, and actuation properties, use of nanotube arrays for electrodes and biosensors, catalyst loaded nanotubes for medical contrast agents, and nanosphere chains for manufacturing composite materials. Overall, this paper shows that "Nanoizing" materials and structures is a hot new technological science that is going to improve many aspects of our lives. These new materials are also generating intellectual property and new opportunities for small companies and universities.
