Nanotechnology, on the other hand, is the actual manipulation, application, and use of nanometer-sized objects and matter to produce different phenomena, or for specific technologies and applications. Nanoscale refers to anything that is in the particular size that is studied, or used for, nanotechnology and nanoscience.

The naked eye cannot see nanoscale items, so specialized technology is used to study these tiny objects. It is very hard for most people to understand just how small a nanometer is.

For reference, a sheet of standard notebook paper has a thickness of approximately , nanometers, which is. When something is reduced to nanoscale, its color, as well as the specific properties it normally has at a larger size, are often altered.

Nanoscience studies these changes in an object and its new properties. Nanotechnology and nanoscience are interdisciplinary fields that combine physics , chemistry, and biology. Universities, companies, and governments often study these fields because it is thought that the applications that may result from nanoscale study could alter every aspect of life. The carbon balls with chemical formula C60 or C70 are formed when graphite is evaporated in an inert atmosphere. A new carbon chemistry has been now developed, and it is possible to enclose metal atoms and create new organic compounds.

A few years later, in , Iijima et al. The strength and flexibility of carbon nanotubes make them potentially useful in many nanotechnological applications. Currently, Carbon nanotubes are used as composite fibers in polymers and beton to improve the mechanical, thermal and electrical properties of the bulk product.

They also have potential applications as field emitters, energy storage materials, catalysis, and molecular electronic components. Schematic of a C60 buckyball Fullerene A and carbon nanotube B.

In , a new class of carbon nanomaterials called carbon dots C-dots with size below 10 nm was discovered accidentally by Xu et al. C-dots with interesting properties have gradually become a rising star as a new nanocarbon member due to their benign, abundant and inexpensive nature [ 29 ].

Possessing such superior properties as low toxicity and good biocompatibility renders C-dots favorable materials for applications in bioimaging, biosensor and drug delivery [ 30 , 31 , 32 , 33 , 34 , 35 ].

Based on their excellent optical and electronic properties, C-dots can also offer exciting opportunities for catalysis, energy conversion, photovoltaic devices and nanoprobes for sensitive ion detection [ 36 , 37 , 38 , 39 ]. In the meantime, nanoscience progressed in other fields of science like in computer science, bio and engineering.

Nanoscience and technology progressed in computer science to decrease the size of a normal computer from a room size to highly efficient moveable laptops. Electrical engineers progressed to design the complex electrical circuits down to nanoscale level. Also, many advances are noticed in smart phone technology and other modern electronic devices for daily uses.

At the beginning of 21st century, there was an increased interest in the nanoscience and nanotechnology fields. During a speech at Caltech on 21 January , President Bill Clinton advocated for the funding of research in the field of nanotechnology.

Three years later, President George W. Bush signed into law the 21st century Nanotechnology Research and Development Act. Recently, a number of studies highlighted the huge potential that nanotechnologies play in biomedicine for the diagnosis and therapy of many human diseases [ 40 ].

In this regard, bio-nanotechnology is considered by many experts as one of the most intriguing field of application of nanoscience. During recent decades, the applications of nanotechnology in many biology related areas such as diagnosis, drug delivery, and molecular imaging are being intensively researched and offered excellent results.

Remarkably, a plethora of medical-related products containing nanomaterials are currently on the market in the USA. One of the most important applications of nanotechnology to molecular biology has been related to nucleic acids. DNA nanotechnology has already become an interdisciplinary research area, with researchers from physics, chemistry, materials science, computer science, and medicine coming together to find solutions for future challenges in nanotechnology [ 44 , 45 , 46 , 47 ].

Notably, years of extensive studied made possible to use DNA and other biopolymers directly in array technologies for sensing and diagnostic applications. Remarkable progresses have been made also in the field of nano-oncology by improving the efficacy of traditional chemotherapy drugs for a plethora of aggressive human cancers [ 48 , 49 ]. These advances have been achieved by targeting the tumour site with several functional molecules including nanoparticles, antibodies and cytotoxic agents.

In this context, many studies showed that nanomaterials can be employed itself or to deliver therapeutic molecules to modulate essential biological processes, like autophagy, metabolism or oxidative stress, exerting anticancer activity [ 50 ]. Hence, nano-oncology is a very attractive application of nanoscience and allows for the improvement of tumour response rates in addition to a significant reduction of the systemic toxicity associated with current chemotherapy treatments.

Nanotechnology has been used to improve the environment and to produce more efficient and cost-effective energy, such as generating less pollution during the manufacture of materials, producing solar cells that generate electricity at a competitive cost, cleaning up organic chemicals polluting groundwater, and cleaning volatile organic compounds VOCs from air. However, the application of computational approaches to nanomedicine is yet underdeveloped and is an exigent area of research.

The need for computational applications at the nano scale has given rise to the field of nanoinformatics. Powerful machine-learning algorithms and predictive analytics can considerably facilitate the design of more efficient nanocarriers. Such algorithms provide predictive knowledge on future data, have been mainly applied for predicting cellular uptake, activity, and cytotoxicity of nanoparticles. Data mining, network analysis, quantitative structure-property relationship QSPR , quantitative structure—activity relationship QSAR , and ADMET absorption, distribution, metabolism, excretion, and toxicity predictors are some of the other prominent property evaluations being carried out in nanoinformatics.

Nanoinformatics has provided a major supplementary platform for nanoparticle design and analysis to overcome such in vitro barriers. Nanoinformatics exclusively deals with the assembling, sharing, envisaging, modeling, and evaluation of significant nanoscale level data and information.

Nanoinformatics also facilitates chemotherapy by improving the nano-modeling of the tumor cells and aids detection of the drug-resistant tumors easily.

Hyperthermia-based targeted drug delivery and gene therapy approaches are the latest nanoinformatics techniques proven to treat cancer with least side effects [ 51 ]. All these progressions in different fields of science have been generally overviewed and summarized in Figure 9. In only a few decades, nanotechnology and nanoscience have become of fundamental importance to industrial applications and medical devices, such as diagnostic biosensors, drug delivery systems, and imaging probes.

For example, in the food industry, nanomaterials have been exploited to increase drastically the production, packaging, shelf life, and bioavailability of nutrients. In contrast, zinc oxide nanostructures display antimicrobial activity against food-borne bacteria, and a plethora of different nanomaterials are nowadays used for diagnostic purposes as food sensors to detect food quality and safety [ 52 ].

Nanomaterials are being used to build a new generation of solar cells, hydrogen fuel cells, and novel hydrogen storage systems capable of delivering clean energy to countries still reliant on traditional, non-renewable contaminating fuels.

However, the most significant advances in nanotechnology fall in the broad field of biomedicine and especially in cancer therapeutics because of their great potential to offer innovative solutions to overcome the limitations deriving by traditional chemotherapy and radiotherapy approaches. Recent advances made in the fields of physic, chemistry and material sciences have provided a number of nanomaterials with unique properties, which are expected to improve the treatment of many tumors otherwise resistant to current therapies.

These innovative biomedical applications are currently exploited in a variety of clinical trials and, in the near future, may support major development in the therapy of cancer. In , the budget for NNI was 1. Still, scientists are working for new breakthroughs in nanoscience and nanotechnology in order to make human life easier and more comfortable.
