A simple and very mild approach for the application of a conductive layer for sheathless electrospray has been developed. A modified 'fairy dust' method is employed in which 2 mm gold particles are applied by a thin layer of silicone on shaped tips. This novel approach comprises fabrications at room

Chromium-gold coated fused silica emitters for electrospray ionization have been fabricated with lifetimes upwards of 100 hours. The coating on these emitters is extremely durable withstanding electrical discharges, abrasion and mechanical stress. Usable flow rates range from 30 nL/min to 1 mL/min u
