Which of the following is not an application of nanomaterials?a) TV and computer monitorsb) Cardiologyc) - Brainly.in? ›

Answer: Explanation: Cardiology is not an application of nanomaterials. TV and computer monitors, Magnetic Resonance Imaging (MRI) and sunscreens and fuel cells are some of the applications of nanomaterials.

The various classical associated features and characteristics of nanotechnology for the medical domain include (1) wound treatment; (2) antibacterial treatments; (3) minimise damage of healthy cells; and (4) nanomedicine diagnostic technique.

There are four main types of intentionally produced nanomaterials: carbon-based, metal-based, dendrimers, and nanocomposites.

Nanomaterials can be used in different applications such as in medicine, electronic device, sunscreens, military applications, photovoltaic cells, paints, catalysts, etc. Some of these do not have an effect on the environment, while others have an effect on it.

Examples of metal-based inorganic nanomaterials are silver (Ag), gold (Au), aluminum (Al), cadmium (Cd), copper (Cu), iron (Fe), zinc (Zn), and lead (Pb) nanomaterials, whereas examples of metal oxide-based inorganic nanomaterials are zinc oxide (ZnO), copper oxide (CuO), magnesium aluminum oxide (MgAl₂O₄), titanium ...

Many products used in everyday life are made with the assistance of nanotechnologies. Cosmetic, pharmaceuticals, sunscreen, powdered food are only few examples of end products containing nano-sized particles (NPs), generally added to improve the product quality.

Nanotechnology is already leading to dramatic improvements in health care. Scientists are using nanoparticles to target tumors, in drug delivery systems, and to improve medical imaging. Some nanoparticle-based treatments are multi-functional; they can both find tumors and carry drugs for treatment.

Nano-engineered materials make superior household products such as degreasers and stain removers; environmental sensors, air purifiers, and filters; antibacterial cleansers; and specialized paints and sealing products, such a self-cleaning house paints that resist dirt and marks.

Furthermore, recombinant DNA technology has made it possible to sequence and analyze the human genome, leading to the discovery of new genes and the identification of genetic mutations that cause disease. This has greatly advanced our understanding of genetics and provided new targets for drug development.

What are the classification and application of nanomaterials? ›

Nanomaterials are classified into three groups based on the length of their diameter dimensions, which are micro porous materials, mesoporous materials, and macro porous materials.

Nanomaterials are usually considered to be materials with at least one external dimension that measures 100 nanometres or less or with internal structures measuring 100 nm or less. They may be in the form of particles, tubes, rods or fibres.

Applications of nanotechnology have emerged with increasing need of nanoparticle uses in various fields of food science and food microbiology, including food processing, food packaging, functional food development, food safety, detection of foodborne pathogens, and shelf-life extension of food and/or food products.

Nanotechnology in electronics improves the capabilities of electronic devices. Moreover, it decreases their weight and power consumption. It improves the density of memory chips. It also reduces the size of transistors used in integrated circuits.

In situ nanoremediation methods entail the application of reactive nanomaterials for transformation and detoxification of pollutants in situ. These nanomaterials have properties that enable both chemical reduction and catalysis to mitigate the pollutants of concern.

Silver is the most common nano-material used in products, followed by carbon-based nano-materials and metal oxides such as TiO2. Nanotechnology is going to pave the way for a revolution in materials, information and communication technology, medicine, genetics, etc.

The most frequently encountered nanomaterials in our daily life include zinc oxide nanoparticles (ZnONPs), titanium dioxide nanoparticles (TiO₂NPs), silica nanoparticles (SiO₂NPs), silver nanoparticles (Ag-NPs), gold NPs (AuNPs), and polymeric nanoparticles (PNPs).

The names of these ingredients must be followed by the word “nano” in brackets”. In the list of ingredients, which shows the exact composition on each cosmetic product, the inorganic UV-blocker (also called mineral UV-Filter) titanium dioxide, for example, can be found as “TITANIUM DIOXIDE (nano)”.
