In a study published in the journal Advanced Functional Materials, scientists developed a nanorobot that can irreversibly capture microplastics in polluted water with high efficiency on a timescale of the order of tens of seconds. As model microplastics, they used spherical particles of about 5 mm in size.<\/p>\n
Using defective and atomic engineering, the scientists were able to control the direction and speed of movement of the nanorobots in water. Titanium dioxide nanotubes, with a diameter of about 250 nm and length of several microns, were prepared by electrochemical anodization. Oxygen defects in the titanium dioxide structure were created by ignition in a hydrogen atmosphere. Platinum atoms were added into the defective structure using deposition techniques.<\/p>\n
The scientists showed that by creating defects in the structure of titanium dioxide, nanorobots move at a higher speed in the x<\/em>–y<\/em> plane. Moreover, the incorporation of platinum led to the phenomenon of negative photogravitaxis, enabling platinum-enriched nanorobots to move against gravity in the z<\/em>-axis direction. Such control over the speed and direction of motion of nanorobots offers potential in a range of environmental, chemical or biomedical applications.[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":" [vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″…<\/p>\n","protected":false},"author":2,"featured_media":6841,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[],"class_list":["post-6840","post","type-post","status-publish","format-standard","has-post-thumbnail","category-featured"],"_links":{"self":[{"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/posts\/6840","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/comments?post=6840"}],"version-history":[{"count":3,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/posts\/6840\/revisions"}],"predecessor-version":[{"id":6844,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/posts\/6840\/revisions\/6844"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/media\/6841"}],"wp:attachment":[{"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/media?parent=6840"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/categories?post=6840"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.techscale.cz\/en\/wp-json\/wp\/v2\/tags?post=6840"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
