What system is used by nanotechnology for drug delivery?
Nano-carrier system (NCS) encapsulates or adsorbs a drug, a therapeutic foreign gene molecule on its surface, and also couples a specific targeting molecule to the surface of the nano-carrier and then binds to a cell surface-specific receptor through a targeting molecule.
What are the various applications of nano pharmacology?
The applications of nanotechnology to pharmacology are reviewed. The potential applications of biochips, nanosensors, bioreactors, neural stem cells, immune nanoparticles, biodegradable polymers, and convection-enhanced drug delivery in the diagnostics and treatment of diseases are discussed.
What is advanced drug delivery system?
The advanced anticancer drug delivery systems utilize the physicochemical profile of morbid cancer cells including abnormal pH, temperature, and oxidative imbalance that function as stimuli to facilitate a sustained drug release. This has been a major success in the current anticancer drug delivery regime.
How might nanotechnology improve the drug delivery process?
Applying nanotechnology to drug delivery should achieve the following benefits:
- Improve the ability to deliver drugs that are poorly water soluble.
- Provide site-specific targeting to reduce drug accumulation within healthy tissue.
- Help retain the drug in the body long enough for effective treatment.
What are the types of drug delivery systems?
Figure 1: Different routes of drug delivery.
- Buccal drug delivery.
- Nasal drug delivery.
- Ocular drug delivery.
- Oral drug delivery.
- Pulmonary drug delivery.
- Sublingual drug delivery.
- Transdermal drug delivery.
- Vaginal/anal drug delivery.
What are advantages of nanoparticles?
The key advantages of nanoparticles are (1) improved bioavailability by enhancing aqueous solubility, (2) increasing resistance time in the body (increasing half life for clearance/increasing specificity for its cognate receptors and (3) targeting drug to specific location in the body (its site of action).
What are nanoparticles advantages?
What are the challenges brought by nanotechnology?
The most immediate challenge in nanotechnology is that we need to learn more about materials and their properties at the nanoscale. Universities and corporations across the world are rigorously studying how atoms fit together to form larger structures.
What are some of the possible applications of nanotechnology in the Philippines?
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.
Can nanostructures be used as a delivery agent for drugs?
Nanomedicines have become well appreciated in recent times due to the fact that nanostructures could be utilized as delivery agents by encapsulating drugs or attaching therapeutic drugs and deliver them to target tissues more precisely with a controlled release [ 10, 19 ].
Is nanotechnology the future of drug targeting?
Therefore, using new drug delivery systems for targeting drugs to specific body parts could be an option that might solve these critical issues [ 9, 10 ]. Hence, nanotechnology plays a significant role in advanced medicine/drug formulations, targeting arena and their controlled drug release and delivery with immense success.
What are nanomedicine and nano delivery systems?
Nanomedicine and nano delivery systems are a relatively new but rapidly developing science where materials in the nanoscale range are employed to serve as means of diagnostic tools or to deliver therapeutic agents to specific targeted sites in a controlled manner.
Why is the use of inorganic nanoparticles on the rise?
These properties let to an increase in the use of inorganic nanoparticles with an emphasis on drug delivery, imaging and therapeutics functions. In addition, nanostructures reportedly aid in preventing drugs from being tarnished in the gastrointestinal region and help the delivery of sparingly water-soluble drugs to their target location.
