All chemicals used in fabrication
including SU8 2002 and KMPR 1010 photoresists, SU8 developer, and
Omnicoat adhesion promoter were purchased from KayukaAM (Westborough,
Massachusetts). Hydroxymethylferrocene (97%), p-aminophenol
(98%), (±)-epinephrine hydrochloride (98%), and monobasic potassium
phosphate (99%) were purchased from Sigma-Aldrich (St. Louis, Missouri).
85 w/w% phosphoric acid (ACS grade) was purchased from Fischer Chemical
(Hampton, New Hampshire). Potassium nitrate (reagent grade) was purchased
from VWR Life Sciences (Radnor, Pennsylvania). A 1,4-dimethyoxybenzene
derivative (C7) was synthesized40 (link) and provided
by the Zhang group from Argonne National Laboratory. A tri(dialkylamino)cyclopropenium
derivative (HS-cyclopropenium) was synthesized41 (link) and provided by the Sanford group from the University of
Michigan, Ann Arbor. Eighteen MΩ DI water was obtained from
a Milli-Q purification system. All other chemicals were used as purchased
without further purification. Glass slides (2” × 3”)
were purchased from Corning Inc. (Corning, New York). Anisotropically
conductive film for making device connections was purchased from 3
M (St. Paul, Minnesota). Photomasks for the device were purchased
from Front Range Photomasks (Phoenix, Arizona).
