Easy Writing of Nanopatterns on a Polymer Film Using Electrostatic Nanolithography

A review on techniques to fabricate silicon oxide arrays for biomolecules patterning

“…They also studied the stability of patterned after several days by AFM imaging and confirmed the pattern remains same as fabricated. Jagadeesan et al [14] have shown some interesting result as at À7 V both raised and grooved patters can be obtained but the reason is not clearly stated.…”

“…2. Raised and grooved patterns due to ramping the tip to different voltage [14]. and it is easy to maintain the relative humidity around 60-70%.…”

“…Jegadesan et al [14] have used AFM anodic oxidation on PMMA (poly(methyl methacrylate)) monolayer coated on silicon wafer and optimized the changes with different bias voltages (À4 to À11 V) at 0.5 lm s À1 scan rate. Fig.…”

“…There are many methods to fabricate well controlled nanostructures, such as oxidation [7][8][9][10][11][12][13][14][15][16][17][18][19], laser [20][21][22], ultraviolet [23][24][25], etching [20,22], and imprint [26,27]. We are working on fabrication of silicon oxide using AFM anodic oxidation and a copper wire assisted homemade setup.…”

Nanotopography Engineering on Homopolymeric Surfaces Using Cold Plasma Generated Charges

“…[13] Block copolymers [14][15][16][17][18][19][20][21] or mixtures of polymers [9,22] have been used as starting materials for the generation of nanopatterned and nanotopography controlled surfaces, to withstand environmental changes such as temperature, solvents, reactive chemical etching, absorption, etc. The nanotechniques for manufacturing nanopattern and nanotopography range from extremely simple ones such as rubbing the substrate [23] or Langmuir-Blodgett films, [24] up to modified AFM (electrostatic nanolithography [25] ) or TEM (carbothermal reduction) [26] analytical instrument operation. Self-assembling nanotechniques [27][28][29][30] are used to generate masks for selective processing of the surface (e.g., etching) or in the direct generation of nanotopography-containing substrates.…”
