The g-CNQDs have the ability to generate reactive oxygen species (ROS).<\/p>\n<p>\u2022 The ROS rapidly interact and damage the immediately available biological macromolecules such as lipids present on the cell membrane or envelope and proteins present on the cellular surface, towards inactivation of the microorganism.<\/p>\n<p>\u2022 The dependence on visible light is also advantageous over regular ultraviolet mediated disinfection, which requires cautious handling of the UV light-emitting devices.<\/p>\n<p>\u2022 This technology will also be simultaneously explored for antiviral efficiency considering its relevance to the current scenario.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>For more such notes, Articles, News &amp; Views Join our Telegram Channel.<\/strong><\/span><\/p>\n<p><span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" title=\"Telegram Link\" href=\"https:\/\/t.me\/triumphias\" target=\"_blank\"><strong>https:\/\/t.me\/triumphias<\/strong><\/a><\/span><\/p>\n<p><span style=\"color: #0000ff;\"><strong>Click the link below to see the details about the UPSC \u2013Civils courses offered by Triumph IAS.<\/strong> <\/span><span style=\"color: #ff0000;\"><strong><a style=\"color: #ff0000;\" title=\"Courses available\" href=\"https:\/\/triumphias.com\/pages-all-courses.php\">https:\/\/triumphias.com\/pages-all-courses.php<\/a><\/strong><\/span><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Relevance: Prelims: Science and technologyWhy in news? \u2022 Institute of Nano Science and Technology (INST), an autonomous institute under the<\/p>\n","protected":false},"author":1,"featured_media":7219,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[123],"tags":[392],"class_list":["post-7676","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-current-affairs","tag-union-public-service-commission-upsc"],"amp_enabled":true,"_links":{"self":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/7676","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/comments?post=7676"}],"version-history":[{"count":2,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/7676\/revisions"}],"predecessor-version":[{"id":7678,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/7676\/revisions\/7678"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/media\/7219"}],"wp:attachment":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/media?parent=7676"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/categories?post=7676"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/tags?post=7676"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
