The invention provides a dispensing apparatus for dispensing nanovolumes of fluid in chemical or biological procedures onto the surface of a substrate, comprising:
a housing having a plurality of sides and a bottom portion having formed therein a plurality of apertures, said sides and bottom portion of said housing defining an interior volume,
one or more fluid transmitting vesicles, mounted within said apertures, having a nanovolume sized fluid holding chamber for holding nanovolumes of fluid, said fluid holding chamber being disposed in fluid communication with said interior volume of said housing, and
dispensing means in communication with said interior volume of said housing for selectively dispensing nanovolumes of fluid from said nanovolume sized fluid transmitting vesicles when the fluid is loaded with said fluid holding chambers of said vesicles, whereby said dispensing means dispenses nanovolumes of the fluid onto the surface of the substrate when the apparatus is disposed over and in registration with the substrate.
本发明提供了一种分配装置,用于在化学或生物程序中将纳米体积的流体分配到基底表面,该装置包括
具有多个侧面和底部的壳体,壳体的侧面和底部形成多个孔,壳体的侧面和底部限定了内部容积、
一个或多个流体传输囊泡,安装在所述孔内,具有纳米体积大小的流体容纳腔,用于容纳纳米体积的流体,所述流体容纳腔与所述外壳的内部容积流体相通,以及
与所述外壳的所述内部容积相通的分配装置,用于在流体装入所述囊泡的所述流体容纳室时,从所述纳米容积大小的流体传输囊泡中选择性地分配纳米容积的流体,从而当设备放置在基底上方并与基底相匹配时,所述分配装置将纳米容积的流体分配到基底的表面上。
