Desktop Dip Pen Nanolitography (DPN) 5000
DPN 5000

DPN is NanoInk's patented process for deposition of nanoscale materials onto a substrate. The vehicle for deposition can include pyramidal scanning probe microscope tips, hollow tips, and even tips on electronically actuated cantilevers.

DPN is an established method of nanofabrication based on atomic force microscope (AFM). It enables precise control of the materials transferred from a tip to a substrate.

Custom-designed nanoscale features are easily fabricated using “ink" comprised of a wide range of materials from nanoparticles and thiols to DNA and proteins.

Humidity control performance specifications:

Humidity range:  Min. = 5% Rh, max. = 75% Rh (below dew point)

Set point stability:  ± 0.5 % Rh

Sensor resolution:  ± 2.0 % Rh
Overshoot amplitude:  0.1 % Rh @ 60 % Rh from a 15% up‐ramp
Humidification ramp rate:  3% Rh/minute
 (> 15 % Rh range using a range > 15% Rh)
Dehumidification ramp rate:  ‐1% Rh/minute (over 20 % Rh) using an air compressor.

Temperature control performance specifications:
Temperature range:  Min. = 2°C less than room temperature max. = up to 10°C greater than room temperature
Set point stability:  ±0.2 °C (given a stable room temperature)
Detection resolution:  0.1 °C for full scale
Overshoot amplitude:  0.5°C
Heating ramp rate:  0.26°C/minute without DPN stage
