Patent ID: 11712549

Abstract:
An object of the present invention is to provide an anti-adhesive/anti-clogging and/or color marked/tinted micro-capillary tube (microtube), microneedle, or micropipette. Typically, the color/tint will be selected such that the tip of the microneedle or micropipette is in contrast (e.g., visually) to the biological material. The tint/color may be selected to contrast the stained biological material. In some aspects, the color mark comprises nanoparticles that are modified by adding a non-adhesive coating/material that minimizes protein adhesion/adsorption. The microtubes and/or micropipettes may be treated with an anti-clogging reagent and an anti-adhesive reagent to prevent or reduce clogging and adhesion of the micropipette or microneedle to biological materials. The microtubes and/or micropipettes may be formed using additive printing processes and additive manufacturing techniques or from micropipette and microneedle pullers.
