For the purpose of angular momentum manipulation tunable piezoelectric metamaterials will be utilized. Applying the spatio-temporal control on the metamaterial properties, the angular momentum of the generated surface wave or the vortex beam will be modified. In both these situations the interaction of the angular momentum with micro-particles will be studied. The possibilities to distinguish them according to their different responses to the angular momentum variations will be discussed. We expect to see changes in the motion patterns of particles of different mechanical properties due to different induced deformations. The experiments will be conducted on the prototypical particles as well as real biological cells.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lkgiy9-6-f3dfd05bc15d0db2579a305adb26d90e\">\n.flex_column.av-lkgiy9-6-f3dfd05bc15d0db2579a305adb26d90e{\nborder-radius:0px 0px 0px 0px;\npadding:20px 0px 20px 0px;\n}\n<\/style>\n<div  class='flex_column av-lkgiy9-6-f3dfd05bc15d0db2579a305adb26d90e av_one_full  avia-builder-el-8  el_after_av_textblock  el_before_av_one_half  first flex_column_div  column-top-margin'     ><section  class='av_textblock_section av-l48g5n3e-5-ebff0784512dfbb65eadcacef45d6669'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h4>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mqde7m-4-28626934dc4a2eba8e3da065f8feb712\">\n.av_font_icon.av-mqde7m-4-28626934dc4a2eba8e3da065f8feb712{\ncolor:#ebb401;\nborder-color:#ebb401;\n}\n.av_font_icon.av-mqde7m-4-28626934dc4a2eba8e3da065f8feb712 .av-icon-char{\nfont-size:25px;\nline-height:25px;\n}\n<\/style>\n<span  class='av_font_icon av-mqde7m-4-28626934dc4a2eba8e3da065f8feb712 avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue889' data-av_iconfont='entypo-fontello' ><\/span><\/span>Partners<\/h4>\n<h5><\/h5>\n<\/div><\/section><\/div>\n<div class='flex_column_table av-237o9w1-e31f98e4cf06d668c03c0d3978576c28 sc-av_one_half av-equal-height-column-flextable'>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-237o9w1-e31f98e4cf06d668c03c0d3978576c28\">\n@keyframes av_boxShadowEffect_av-237o9w1-e31f98e4cf06d668c03c0d3978576c28-column {\n0%   { box-shadow:  0 0 0 0 #d3d3d3; opacity: 1; }\n100% { box-shadow:  0 0 10px 0 #d3d3d3; opacity: 1; }\n}\n.flex_column.av-237o9w1-e31f98e4cf06d668c03c0d3978576c28{\nbox-shadow: 0 0 10px 0 #d3d3d3;\nborder-width:2px;\nborder-color:#cccccc;\nborder-style:solid;\nborder-radius:10px 10px 10px 10px;\npadding:20px 20px 20px 20px;\n}\n<\/style>\n<div  class='flex_column av-237o9w1-e31f98e4cf06d668c03c0d3978576c28 av_one_half  avia-builder-el-11  el_after_av_one_full  el_before_av_one_full  first flex_column_table_cell av-equal-height-column av-align-bottom shadow-not-animated  column-top-margin'     ><section  class='av_textblock_section av-l48gdxv4-001b415f9b481b71bb8f83f4347101b1'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h4><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-42329\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def-300x110.jpg\" alt=\"\" width=\"300\" height=\"110\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def-300x110.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def.jpg 340w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/h4>\n<h4><strong>Institut d\u2019Electronique, de Micro\u00e9lectronique et de Nanotechnologie, IEMN<\/strong><\/h4>\n<h5><em>Coordinateur : S.
