The Use Of Nanomedicine - 741 Words

The essence of pharmaceutical treatment is for the administered drug to be present at the site of action in a concentration that exceeds the minimum effective concentration. This is not always the case most times because of some unchallengeable properties of the drug. As a matter of fact, there have been several effective therapies made available for many disease conditions that have failed in their effectiveness because of their inability to reach the site of action. The possible reasons for the poor bioavailability of these drugs at the required site of action include; their inability to permeate biological membranes, poor solubility in water as well as the drugs been rapidly broken down through metabolism and cleared from the body†¦show more content†¦Nanocellulose are an excellent choice material because they are obtained from cellulose which is abundantly available in nature, renewable, biodegradable, with low cost, low density, low ecological toxicity risk, low cytotox icity to a range of animals and human cells and unique mechanical properties. It is an evolving renewable polymeric nanomaterial that holds promise in diverse applications including food and pharmaceuticals. Interest in the production and utilization of nanocellulose have in recent times attracted a lot of attention from both academic and industrial researchers resulting from their mechanical strength, transparency and proven biocompatibility. This attention is mirrored in the flow of publications in scientific literature in recent years. Exceptional discussions on the chemistry, preparation, and the general properties of nanocellulose are obtainable from numerous literatures.The surface chemistry of nanocellulose materials makes them an interesting podium for ready and easy functionalization because they are almost entirely made of hydroxyl groups. This tendency coupled with their biocompatibility is propelling their use within different (bio)materials. Nanocellulose materials are in three categories depending on whether the cellulose is of bacterial origin or derived from theShow MoreRelatedThe Synthesis Of Nannomaterials1734 Words   |  7 PagesChemical synthesis of nanomaterials for drug delivery most commonly involves the synthesis of nanometal compounds, polymer nanocomposites and quantum dots. The original synthesis techniques for these nanomedicine applications involve toxic reagents and waste products. Green che mistry initiatives are attempting to produce nanometals, composites and quantum dots without the toxicity and waste associated with early methods. Nanometals are an area of high interest in for drug delivery due to their magneticRead MoreEssay on Use of Nanotechnology in Medecine2565 Words   |  11 Pagesnavigated to his brain to mechanically destroy the clot and save the spy along with his secret information. This idea has evolved from science fiction into what is today the branch of science and technology that is known as Nanomedicine. The potential benefits of Nanomedicine are to possibly develop a cure for cancer, cure diabetes, suppress genetic defects, and even cure mental illness. Nanorobots could be injected into the blood stream where they could wipe out viruses, bacteria, and other harmfulRead MoreNanomedicine: A Tiny World Essay2111 Words   |  9 PagesNanomedicine: A Tiny World Medical technology is advancing faster today than ever before allowing for easier, faster, simpler and advances in medical devices, procedures and diagnosis’. Medical devices also keep getting smaller; very, very small – the size of a nanometre. Nanotechnology is technology that controls matter at a molecular level. Nano means one billionth of a metre which is the range of an atom. (Appendix 1, Figure 1) From its beginning, nanotechnology has been more of a dream thanRead MoreNanotechnology Case Study813 Words   |  4 PagesBiotechnological solutions to a variety of illnesses, surgical procedures, genetic exploits and a myriad of other things are now in the form of nanotechnology. Big pharmaceutical companies now refer to many of their medications, in fact, as nanomedicines, which alludes to the nanotechnological inputs in pills that improve delivery methods and even deploy nanoparticles for specific purposes on occasion. A new study actually illustrates how attaching RNA nanoparticles that masquerade as antibodiesRead MoreBreast Cancer Treatment And Therapy With Nanomedicine1054 Words   |  5 PagesBreast cancer treatment and therapy with nanomedicine is a fad nowadays and rightfully so, it is the need of the minute. The incidence rate of breast cancer has witnessed a minimum 10-fold increase in the past few decades. The mortality rate in women is rising and breast cancer is a m ajor contributing factor. Due to several changes in the hormonal, nutritional and environmental factors over the years, there is a shift observed in the rise of breast cancer. At a point, conventional mammography forRead MoreApplication Of Nanotechnology : Diagnosis And Treatment Of Tumors Essay1080 Words   |  5 Pageshas emerged recently as one of the most propitious fields in cancer treatment [10]. Nanomedicine (the medical application of nanotechnology) has incredible potential for revolutionizing cancer therapeutics and diagnostics by developing ingenious biocompatible nano- composites for drug delivery purposes, which represent the most pertinent application of nanoparticles [6]. Recent years have witnessed unprecedented use of nanocarriers (particularly in the size range from 10 nm to 100 nm) as an emergingRead MoreA Study On The Gecko Adhesive System1909 Words   |  8 Pagesobjects measured in nanometers. To give a better perspective of size, one nanometer is one-billion th of a meter, or about eighty thousand times smaller than the diameter of a single human hair. A particular application of nano-materials in nature is the use of nano-finger tips which allow geckos to walk on walls. The gecko adhesive system incorporates one million foot hairs or setae in on each finger. One hair or seta contains a thousand of spatula tips which allow the geckos to attach to the wall. SyntheticRead MoreIs Gold Isn t Just For Olympics? Essay1802 Words   |  8 Pagescancer patients we have still not found a 100% cure to cancer. One such innovation that is providing hope to cancer patients is nanomedicine. Nanomedicine is a non-invasive cancer treatment that kills cancer cells without hurting surrounding healthy tissue and relatively fewer harmful side effects. Nanomedicine is an emerging field and today there are more than 1500 nanomedicine cancer therapies that are registered for clinical trials.
