The integration of microfluidic devices with microneedles offers better fluid management abilities, resulting in a more advanced level of controlled drug delivery

(A) An illustration of the proposed device fabricated by stereolithography 3D printing, with three separate microfluidic inlets and microneedles (MN) as the outlet. The zoomed section shows the MNs.
