ALIGNMENT AND ROTATION OF JANUS MICROPARTICLES IN RESPONSE TO ACCELERATION

Gravitational Janus microparticle having, a center-of-mass, a center-of-volume, and a non-uniform density, wherein: the center-of-mass and the center-of-volume are distinct. When suspended in a fluid, the microparticle substantially aligns with either: i) the gravitational field; or ii) the directio...

Beschreibung
Zusammenfassung:	Gravitational Janus microparticle having, a center-of-mass, a center-of-volume, and a non-uniform density, wherein: the center-of-mass and the center-of-volume are distinct. When suspended in a fluid, the microparticle substantially aligns with either: i) the gravitational field; or ii) the direction of an acceleration, such that the Janus microparticle is in substantial rotation equilibrium. After perturbation from substantial rotational equilibrium, the Janus microparticle reversibly rotates to return to substantial rotational equilibrium. The gravitational Janus microparticle may comprise at least two portions, each having distinct physical and/or chemical characteristics, wherein at least one portion provides a detectable effect following rotation and alignment of the microparticle. L'invention concerne une microparticule Janus gravitationnelle ayant un centre de masse, un centre de volume et une densité non uniforme, dans laquelle : le centre de masse et le centre de volume sont distincts. Lorsqu'elle est en suspension dans un fluide, la microparticule s'aligne sensiblement avec : i) le champ gravitationnel ; ou ii) la direction d'une accélération, de telle sorte que la microparticule Janus est sensiblement en équilibre rotatif. Après perturbation de l'équilibre rotatif sensible, la microparticule Janus pivote de façon réversible et revient à l'équilibre rotatif sensible. La microparticule Janus gravitationnelle peut comprendre au moins deux parties, présentant chacune des caractéristiques chimiques et/ou physiques distinctes, au moins une partie produisant un effet détectable après la rotation et l'alignement de la microparticule.
