biological objects at micrometric down to nanometric scales promises tremendous development in fields as diverse as microrobotics, microfluidics, tissue engineering or micro\/nano- medicine.<\/p>\n<p>In this regard, acoustical tweezers is a prominent technology since it is non-invasive, biocompatible label-free and enables trapping forces several orders of magnitudes larger than their optical counterparts at same actuation power, hence preventing deleterious heating.<\/p>\n<p>Yet, the widespread dissemination of this technology has been hindered by severe limitations of current systems in terms of selectivity and\/or miniaturization and integrability. In this work, the authors have brought the technology to the next level by developing the first flat, transparent, single electrodes selective acoustical tweezers.<\/p>\n<p>These tweezers rely on spiraling transducers obtained by folding a spherical acoustical vortex on a flat piezoelectric substrate. The authors demonstrate the ability of these tweezers to grab and displace micrometric objects in a standard microscopy environment with unique selectivity.<\/p>\n<blockquote>\n<p><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2019\/04\/4.cover-source.gif\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-36410 alignleft\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2019\/04\/4.cover-source.gif\" alt=\"\" width=\"83\" height=\"105\" \/><\/a>Reference: M.
