Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
Nanotechnology is the science and engineering of functional systems at the molecular scale. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up making complete, high-performance products. One nanometer (nm) is one billionth, or 10 −9, of a meter.
A video on the health and safety implications of nanotechnology. The health impacts of nanotechnology are the possible effects that the use of nanotechnological materials and devices will have on human health. As nanotechnology is an emerging field, there is great debate regarding to what extent nanotechnology will benefit or pose risks for ...
The composition of the nanoparticle can be chosen according to the target environment or desired effect. For example, liposome-based nanoparticles can be biologically degraded after delivery, [6] thus minimizing the risk of accumulation and toxicity after the therapeutic cargo has been released.
Nanotechnology's ability to observe and control the material world at a nanoscopic level can offer great potential for construction development. Nanotechnology can help improve the strength and durability of construction materials, including cement, steel, wood, and glass. [9] By applying nanotechnology, materials can gain a range of new ...
Conversely, many new medical technologies involving nanoparticles as delivery systems or as sensors would be examples of nanobiotechnology since they involve using nanotechnology to advance the goals of biology. The definitions enumerated above will be utilized whenever a distinction between nanobio and bionano is made in this article.
An example is a sensor having a switch approximately 1.5 nanometers across, able to count specific molecules in the chemical sample. The first useful applications of nanomachines may be in nanomedicine. For example, [9] biological machines could be used to identify and destroy cancer cells.
Examples of gold nanoparticles are gold nanoshells and nanocages. [3] Different types of nanomaterial being used in nanocarriers allows for hydrophobic and hydrophilic drugs to be delivered throughout the body. [ 5 ]
