PARTICLE CAPTURE DEVICES AND METHODS OF USE THEREOF
First Claim
1. A particle patterning device comprising:
- a first substrate;
at least one capture unit positioned such that the top of said capture unit is adhered to or contiguous with said first substrate, said capture unit comprising;
a first chamber comprising at least one opening, sized to trap and accommodate a single particle; and
a second chamber comprising at least one opening, sized to trap and accommodate a single or more than a single particle;
wherein an opening of said first chamber faces a direction opposite to that of an opening of said second chamber, and said opening of said first chamber is contiguous with a side of said capture unit, said opening of said second chamber is contiguous with an opposite side of said capture unit;
optionally a second substrate positioned proximally to or adhered to a bottom of said capture unit or a portion thereof;
a conduit through which first flow may be induced in said device, such that fluid flow is accommodated at least between said capture unit and said second substrate and particles positioned within said first or second chamber are subject to said fluid flow; and
optionally, a second conduit through which a second flow may be induced in a direction opposite to that of said first flow.

Abstract
The present invention provides a device and methods of use thereof in microscale particle capturing and particle pairing. This invention provides particle patterning device, which mechanically traps individual particles within first chambers of capture units, transfer the particles to second chambers of opposing capture units, and traps a second type of particle in the same second chamber. The device and methods allow for high yield assaying of trapped cells, high yield fusion of trapped, paired cells, for controlled binding of particles to cells and for specific chemical reactions between particle interfaces and particle contents. The device and method provide means of identification of the particle population and a facile route to particle collection.
