What are nano drugs?
Nano drugs are a revolutionary and ubiquitous science of the 21st century; a nano drug is the application of nanotechnology in the medicinal field that has the potential to significantly change the course of diagnostics and treatment of various life-threating diseases.
What nano Means?
The term “nano” comes from ancient Greek and means “dwarf” (nános = dwarf). However, the nanosciences deal not with garden gnomes but with tiny nanostructures only a few nanometers in size (<100 nm). Used as a prefix, “nano” denotes 10-9, just as “kilo” denotes 103 and “milli” 10-3.
What drugs have nanoparticles?
Several anti-cancer drugs including paclitaxel, doxorubicin, 5-fluorouracil and dexamethasone have been successfully formulated using nanomaterials. Quantom dots, chitosan, Polylactic/glycolic acid (PLGA) and PLGA-based nanoparticles have also been used for in vitro RNAi delivery.
How does nano medicine work?
By packaging up drugs and moving them through the body directly to diseased cells to reduce collateral damage, in theory, nanomedicine allows higher doses of drugs to be used. Nanomedicine has great potential to safely treat children’s cancer.
What are nanoparticles give examples?
An example of how the unique properties of nanoparticles have been put to use in a nanocomposite material is the modern rubber tire, which typically is a composite of a rubber (an elastomer) and an inorganic filler (a reinforcing particle), such as carbon black or silica nanoparticles.
Where are nanoparticles used?
Nanoparticles are now being used in the manufacture of scratchproof eyeglasses, crack- resistant paints, anti-graffiti coatings for walls, transparent sunscreens, stain-repellent fabrics, self-cleaning windows and ceramic coatings for solar cells.
What makes nano special?
Nanoscale materials have far larger surface areas than similar masses of larger-scale materials. As surface area per mass of a material increases, a greater amount of the material can come into contact with surrounding materials, thus affecting reactivity.
What is nano used for?
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.
What are nanoparticles for?
How are nanomaterials used in the delivery of drugs?
Nano-drug delivery systems (NDDSs) are a class of nanomaterials that have abilities to increase the stability and water solubility of drugs, prolong the cycle time, increase the uptake rate of target cells or tissues, and reduce enzyme degradation, thereby improve the safety and effectiveness of drugs ( Quan et al., 2015; Gupta et al., 2019 ).
Are there any problems with the nano drug delivery system?
Nano-drug delivery systems (NDDSs) provide a new drug delivery method for the treatment of CVDs with the development of nanotechnology, demonstrating great advantages in solving the above problems. Nevertheless, there are some problems about NDDSs need to be addressed, such as cytotoxicity.
How are nano-form drugs different from other drugs?
These drugs in the nano-form possess unique features such as high surface to mass ratio and quantum-size effects such as electron confinement with absorption and drug carrier ability . These features play a crucial role to overcome the challenge of low therapeutic absorption associated with phytochemicals as drugs and new chemical entities.
How are nanotechnology used in the field of Medicine?
Nanotechnology employs curative agents at the nanoscale level to develop nanomedicines. The field of biomedicine comprising nanobiotechnology, drug delivery, biosensors, and tissue engineering has been powered by nanoparticles [ 17 ].
