Materials science is an interdisciplinary area involving the properties of matter and its applications to various areas of engineering and science.
It includes elements of applied chemistry and physics, as well as mechanical, chemical,electrical, and civil engineering.
Biomaterials are the non-drug molecules which are considered to interact with the biological system either as a part of medical device or replace or repair to any damaged tissues or organs. Biomaterials can be derived either naturally orsynthetically. Tissue engineering has the possible to achieve this by combining materials engineering and design with cell therapy. Biomaterials can give physical supports for powerful topographical, engineered tissues and chemical cues to guide cells. Biomaterials engineering involvessynthesis, processing and characterisation of novel materials, including glasses, cements, polymers, proteins, hybrids and textile composites. Introducing nanoscale cues such as Nano topography or nanoparticles as therapeutic agents provide an exciting approach to moderate cell behaviour.
At the atomic level magnetism can be well-defined through the overlap of electron wave functions, when taking their spin interactions into account. On the nano meter length scale it becomes tougher to predict the behaviour of a magnetic system. When minimizing the size of the magnetic material the number of domains within the material will be reduced until only a single domain is obtained. By having single domains it is probable to produce strong permanent magnets. If the size is minimized beyond a certain boundary the sample converts as superparamagnetic and does no longer hold any ferromagnetism.
Nanofabrication is of attention to computer engineers because it opens the door to super-high-density memory chips and microprocessors. It has been recommended that each data bit could be stored in a single atom. Carrying this promote, a single atom might even be able to represent word of data or a byte. Nanofabrication has also gathered the attention of the military, the aerospace industry, and the medical industry.
Nanocarriers have been developed for efficient drug delivery and diagnostic tools. Nanocarrier enables an effective, targeted biomolecular interaction in order to lower side effects caused during the treatment. Here, we review the problems associated with the conventional drug development and its delivery system
Nanotechnology is impacting the many product that integrate nanomaterials field unit already in a very type of items; several of which individuals don't even notice contain nanoparticles, products with recent functions starting from easy-to-clean to scratch-resistant. Samples of those clothing is more stain repellant, car bumpers are made lighter, cell phone screens are lighter weight, sun cream is more energy resistant,synthetic bones are stronger. Nanotechnology applications area unit presently being researched tested and in some cases already applied across the entire spectrum of food technology, packaging and food supplements, from agriculture to food processing.
Polymer nanocomposites contains of a polymer or copolymer having Nano particles isolated in the polymer matrix. Polymer nanotechnology group will develop enabling methods for the patterning of functional surfaces. Nanotechnology has made important contributions to the formulation of sealants, adhesives, potting, coatings, and encapsulation compounds. Nanoparticle fillers such as bentonites, nano-sized silica particles and zeolites have lead to the growth of products with enhanced: thermal stability, tensile strength, thermal conductivity, transparency, chemical resistance.
Colloidal nanocrystals are prepared with control shape, composition, over size and are used as precursors to provide supported systems of interest in different areas of catalysis
Nanostructures are used to create specific nanodevices for the handling of biological systems at the molecular level, and this is what currently describes nanomedicine. So far, the addition of nanoparticles with biology has led to the development of contrast agents, imaging approaches, diagnostic devices, drug delivery therapy andadvanced therapy applications. Nanomedicine offers numerous advantages in everyday clinical practice, taking into consideration the nonâ€invasive approach of the samples used, fast reaction times, specificity, and sensitivity that nanoparticles can offer.
Nanorobotics is technology creating machines or robots at nearly to the scale of a nanometer (10-9). nano robotics mentions to the still primarily theoretical nanotechnology engineering discipline of designing and construction of nanorobots. Nanorobots (nanoidsor nanobots) are usually devices ranging in size from 0.1-10 micrometres and built of molecular or nanoscale components. No artificial non-biological nanorobots designed; they remain a hypothetical theory at this time. Additional meaning frequently used is a robot which permits precision interactions with nanoscale objects, or can manipulate with nanoscale resolution. Following this meaning even a large apparatus such as an atomic force microscope can be considered a nanorobotic instrument when configured to perform nanomanipulation. Macroscalerobots orMicrorobots which can transfer with nanoscale precision can also be considered nanorobots.
