We present a novel method for the direct, centrifugally induced fabrication of small alginate beads displaying adjustable diameters between 180 mum and 800 mum by polymer-tube micronozzles. The size distribution features a CV of 7 - 16 % for the main peak. Up to 600 beads per second and channel are issued from the micronozzle through an air gap towards a standard lab tube ("Eppi") attached to the rotor spinning and containing a curing agent. At spinning frequencies between 5 Hz and 28 Hz, the… CONTINUE READING
