Nanotechnology an Introduction
Nanotechnology in cancer treatment and water purification is expected to increase at a rapid pace. Nanotechnology is implicated in the production of devices and elements at a nanoscale while enhancing efficiency and achieving better outcomes. One of the significant sectors where nanotechnology has gained extensive usage is the electronics and computing segment. With the aid of nanotechnology, computers have become more petite as the transistors and semiconductors within them have decreased in size. Modern computers have become faster, efficient, and capable of storing enormous data volumes.
Meantime, nanotechnology is also prevalent in the textile segment with the growth of smart fabric. The smart fabric is a variety of textile that is more durable than traditional fabric and extends more functionality to the wearer, it doesn’t wrinkle. Nanotechnology is also utilized in common objects such as furniture where nanocoating is being used to restrict dirt stains and make them waterproof. To obtain the same objectives, nano-coating is applied to cars as well. Nano–coating, known as a ceramic coating is the technique of using a surface layer that resists dry particles, oil, dirt, and water, for example, nano-coating can make the exterior scratch or bacterial resistant. Nano-coating is used on expensive furniture to avoid them getting spoilt. Nano-coating is also used by industries such as automotive.
Nanotechnology is also bringing innovation to the healthcare segment. With the aid of nanotechnology, researchers are now studying ways to utilize nanoparticles for a more effective way of delivering medications and other substances. Interestingly, nanotechnology is also being implemented in agriculture. With the help of nano pesticides, this can enhance the productivity of crops while diminishing the adverse effects generated by conventional pesticides. The food industry is also expected to advance the utilization of nanotechnology to improve the quality and flavor of food and extend shelf life.
Nanotechnology in treatment of cancer
Nanotechnology in cancer treatment improves chemotherapy and decreases its unfavorable effects by controlling drugs to selectively target cancer cells. It leads to the surgical resection of tumors with greater levels of precision and improves the effectiveness of radiotherapies and other modern treatment alternatives. The effect is limited risk to the patient and enhanced endurance possibilities.
Researchers are creating novel therapeutics with recently found nanoparticles that have unique properties to be leveraged in medical science. Small-sized nanoparticles can be encapsulated in tiny pharmaceutical compounds. The comparatively wide surface area of nanoparticles enables them to be enriched with strands of DNA, ligand, peptides, or neutralizers. This gives the nanoparticle added functionality that improves the therapeutic impact and helps deliver a nanoparticle to a specific location. Hence, nanoparticles expedite combination drug distribution and multi-modality therapy. The re-radiation properties and energy absorption of nanoparticles allow them to develop hyperthermia and laser ablation treatments, which agitate diseased tissue.
The basic use of nanotechnology in cancer treatment (oncology) is within the delivery of medications. Research has revealed that nanotechnology in cancer usage has been utilized to produce multiple systems that enhance the pharmacokinetics of pharmaceuticals and diminish toxicities. These systems restrict the adverse effects of the drugs and increase a patient’s recovery rate.
Nanoparticle in cancer treatment as an end application is growing rapidly, with significant growth in nanoparticle packages, proactive pharmaceutical components to aid the exploration of a wider range of active ingredients, and the founding of surface coatings and immunogenic cargo as an adjuvant to nanoparticle-mediated treatment, stand-alone and radio- and chemotherapy therapies.
Immunotherapy has been reinforced as an interesting and useful alternative for many types of cancer and this focusses on increasing the efficiency of the immune system. The proportion of patients reacting confidently to immunotherapy remains low, with just 15% of patients confirming an actual response rate. This is associated with the multiple immune-evasion practices of the tumor. To further boost the efficiency of the immune system, nanotechnology in cancer treatment is being leveraged to maintain the spatiotemporal control of the immune system. The belief is that naturally, the immune system is spatiotemporally regulated. Hence, to work efficiently, treatments that affect the immune system should also be spatiotemporally regulated.
Nanotechnology in water treatment
Nanotechnology has been extended to help monitor and cleanse polluted water sites in diverse ways. Firstly, it aids build affordable and accessible means of purifying natural drinking water reservoirs. These systems provide rapid, cost-effective exposure and handling of water impurities, technology that is priceless to emerging economies where safe drinking water is not achieved.
Technicians have utilized nanotechnology to build thin-film membranes with nanopores to provide energy-efficient desalination. The efficiency and effectiveness of this technology are about two to five times more than the current practices to refine water.
Experts have used nanotechnology to discover new techniques to clean up industrial water pollutants from groundwater reservoirs. Lastly, scientists have favorably acquired a way of cleansing oil from water. The discovery involves a nano fabric composed of small wires of potassium manganese oxide knitted collectively that can absorb 20 times its weight, hence filtering oil from water.
