What are Nanoproducts used for?
The majority of nanotechnology products are usually used in healthcare and fitness, home and garden, automotive, appliances, coatings, electronics, foods and beverages areas. The Future Markets (2012) reported that the worldwide nanomaterial production will be over 340,000 tons by the end of 2016.
What are inorganic nanocrystals used for?
Inorganic nanoparticles have gained significant attention in preclinical development as potential diagnostic and therapeutic systems in oncology for a variety of applications, including tumor imaging, tumor drug delivery or enhancement of radiotherapy.
What is chemical functionalization?
Functionalization is the process of adding new functions, features, capabilities, or properties to a material by changing the surface chemistry of the material. It is a fundamental technique used throughout chemistry, materials science, biological engineering, textile engineering, and nanotechnology.
What nanoparticles are commonly used?
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.
What is the difference between organic and inorganic nanoparticles?
Organic nanoparticles mainly include polymers, exosomes, liposomes, protein-based nanoparticles etc., while inorganic nanoparticles consist of silica nanoparticles, metal nanoparticles, carbon nanotubes, quantum dots and so forth [2, 3] .
Can nanotechnology cure diseases?
Nanomedicine — the application of nanomaterials and devices for addressing medical problems — has demonstrated great potential for enabling improved diagnosis, treatment, and monitoring of many serious illnesses, including cancer, cardiovascular and neurological disorders, HIV/AIDS, and diabetes, as well as many types …
Why is surface functionalization?
Surface functionalization is an effective and often simpler way of altering the surface properties of a material or device to achieve specific goals such as inducing a desired bioresponse or inhibiting a potentially adverse reaction.
What is material functionalization?
What is functionalization in metabolism?
Description. Phase 1 of metabolism is concerned with functionalization, that is the introduction or exposure of functional groups on the chemical structure of a compound. This provides a ‘handle’ for phase 2 conjugating species with which to react with.
How are nanoparticles used in medicine?
Abstract. Researchers today are able to encapsulate medicine in nanoparticles, the size of viruses. The nanoparticles are effective for drug delivery—the delivery of the medicine to the body—because they can very precisely find diseased cells and carry the medicine to them.
What are nanosensors in food?
Nanosensors can detect pathogenic bacteria, food-contaminating toxins, adulterant, vitamins, dyes, fertilizers, pesticides, taste and smell. Food freshness can be monitored using time–temperature and oxygen indicators. Product authenticity and brand protection can be assessed using invisible nanobarcodes.
What is nanoparticle functionalization and why is it important?
Learn more. Functionalization enhances the properties and characteristics of nanoparticles through surface modification, and enables them to play a major role in the field of medicine. In molecular imaging, quality functional images are required with proper differentiation which can be seen with high contrast to obtain viable information.
How do chemists make nanoparticles functional?
While tailoring particle interfaces is a challenging task, chemists have a well-equipped toolbox to provide functionality through synthesis. 8Using different strategies, nanoparticles have been functionalized with a variety of ligands such as small molecules, surfactants, dendrimers, polymers, and biomolecules.
How are nanoparticles used to treat cancer?
Nanoparticles coated with proteins and antibodies can bind to cell surface receptors, providing targeted delivery. For example, multivalent gold and silver nanoparticles were engineered by loading Herceptin, an antibody to the Her-2 receptor overexpressed in ovarian and breast tumor cells.
How does the surface charge of nanoparticles affect their cellular uptake?
The surface charge of small molecule coated nanoparticles likewise dictates their interaction with cell surface molecules and hence their cellular uptake. 18In general, nanoparticles functionalized with positively charged ligands exhibit higher internalization into cells compared to the neutral and negatively charged particles.
