Research has proved that drinking tea brings various\nhealth benefits. In addition to burning fat and preventing cardiovascular\ndisease, recently, a study showed that the use of nanoparticles extracted from\ntea can actually destroy lung cancer cells.<\/p>\n\n\n\n<p>Nanoparticle is actually a kind of artificially made microparticles with a size not exceeding 100 nanometers. The morphology can be latex, polymer, ceramic particles, metal particles and carbon particles. In recent years, they have been increasingly used in medicine, cosmetics, environmental protection, even food industry.<\/p>\n\n\n\n<p>Tea, an aromatic beverage, is now popular\naround the world for its good taste and health care function. According to\nresearch, many of the potential beneficial effects of tea against cancer have\nbeen attributed to the strong antioxidant activity of tea polyphenols, but in\nthe latest study, scientists created <a href=\"https:\/\/www.cd-bioparticles.com\/product\/quantum-dots-list-169.html\">quantum\ndots<\/a>, or nanoparticles, from tea extracts, and\nfilled them into nanoprobes to fight lung cancer. The research was published in\nthe journal <em>Applied Nano Materials<\/em> titled <em>Green-Synthesis-Derived CdS\nQuantum Dots Using Tea Leaf Extract: Antimicrobial, Bioimaging, and Therapeutic\nApplications in Lung Cancer Cells<\/em>.<\/p>\n\n\n\n<p>Many anti-cancer drugs are small hydrophobic\nmolecules. They have low water solubility, high biodegradation, and their lack\nof specificity in the distribution of organisms as well as off-target toxicity\nare also obstacles in drug development. In contrast, these tiny particles\ncalled quantum dots are completely safe and non-toxic. <\/p>\n\n\n\n<p>The diameter of quantum dots is less than 10\nnanometers, which is 400 times thinner than human hair and is usually\nchemically synthesized. However, the production process of quantum dots is quite\ncomplicated and expensive, and may produce a series of toxic effects. Therefore,\nthe researchers explored a kind of non-toxic production alternative based on\nplant. <\/p>\n\n\n\n<p>Firstly, the tea extract was mixed with chemicals\nincluding cadmium sulfate and sodium sulfide. After incubation of these materials,\nquantum dots were created. Then, they used these dots to fight against cancer\ncells, and the result showed that nanoparticles have anti-cancer properties similar\nto Cisplatin, a widely used chemotherapy drug. The result also showed that quantum\ndots penetrated into the nanopores of cancer cells and destroyed 80% of cancer\ncells.<\/p>\n\n\n\n<p>\u201cOur research confirmed that these quantum dots can play a positive role in the inhibition of lung cancer cells\u2019 growth.\u201d Introduced by one of the researchers, \u201cAnd we think quantum dots will have broad prospects for exploring new cancer treatments. On the basis of this discovery, we will do further research in this new cancer treatment hoping to build a quantum dot factory so that we can fully explore the potential application range of quantum dots.\u201d <\/p>\n\n\n\n<p>In conventional treatments, people may receive surgery, radiation therapy, chemotherapy, targeted or combination therapy according to the type of lung cancer and doctor\u2019s diagnosis. This discovery is undoubtedly good news for lung cancer patients for they may have another choice in the future. After all, using green tea to fight cancer will have a very high cost performance without any side effects comparing with other cancer treatments. <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Reference:<\/p><p>Kavitha, S., et al.
