Claim:
1. A method for injecting microparticles into a microfluidic channel by means of injecting means which comprises a tip through which said microparticles are intended to exit when being injected, said microfluidic channel having an end opening out in a sidewall of an inlet well, and the microparticles are not symmetrical about a plane perpendicular to their longitudinal axis and comprise a top side and a bottom side which comprises protruding means, wherein the method comprises the steps of: a) positioning said tip above at least a zone of said sidewall and at a predetermined distance (d) therefrom, said predetermined distance (d) being in the range of 0.5 mm to 5 mm, wherein the surface of said sidewall being inclined at an angle (γ) of about 10° to 80° with respect to the horizontal plane; and b) injecting the microparticles into said inlet well so that the microparticles come into contact with or in the vicinity of said zone, and then slides on the sidewall before entering said end of the microfluidic channel with their bottom sides facing a bottom wall of the microfluidic channel.
