Patent number: 10915023Abstract: A crosslinked self-assembled monolayer (SAM), comprising surface groups containing a nitrogen-heterocycle, was formed on an oxygen plasma-treated silicon oxide or hafnium oxide top surface of a substrate. The SAM is covalently bound to the underlying oxide layer. The SAM was patterned by direct write methods using ultraviolet (UV) light of wavelength 193 nm or an electron beam, forming a line-space pattern comprising non-exposed SAM features. The non-exposed SAM features non-covalently bound DNA-wrapped carbon nanotubes (DNA-CNT) deposited from aqueous solution with a selective placement efficiency of about 90%. Good alignment of carbon nanotubes to the long axis of the SAM features was also observed. The resulting patterned biopolymer features were used to prepare a CNT based field effect transistor.Type: GrantFiled: November 3, 2017Date of Patent: February 9, 2021Assignee: International Business Machines CorporationInventors: Shu-Jen Han, Brian Lin, Hareem T.

Patent number: 9868870Abstract: A thermo-responsive shear-thinning photo-curable composition comprises water, a linear amphiphilic polyether ABA triblock copolymer comprising at least one pendent ene group (*—CH?CH2) capable of undergoing a thiol-ene reaction, a water-soluble crosslinking agent comprising two or more methylenethiol groups (*—CH2SH), and a photoinitiator. Under non-shear conditions and a triblock copolymer concentration suitable for direct-write printing, the composition is a viscoelastic solid (hydrogel) at a temperature of about 15° C. to about 45° C., and is a free-flowing liquid (sol) between 0° C. and about 10° C. The hydrogel form can be shear-thinned at about 15° C. to about 45° C. to form a sol suitable for a direct-write printer using an extruding print-head. The compositions covalently crosslink when flood-exposed to ultraviolet radiation. The compositions have utility in forming three-dimensional scaffolds for growing living cells.Type: GrantFiled: March 16, 2016Date of Patent: January 16, 2018Assignee: International Business Machines CorporationInventors: Amanda C.

Patent number: 8986596Abstract: A method of preparing particles comprises forming by optical lithography a topographic template layer disposed on a surface of a substrate, which is suitable for spin casting. The template layer comprises a non-crosslinked template polymer having a pattern of independent wells therein for molding independent particles. Spin casting a particle-forming composition onto the template layer forms a composite layer comprising the template polymer and the particles disposed in the wells. The composite layer is removed from the substrate using a stripping agent that dissolves the template polymer without dissolving the particles. The particles are then isolated.Type: GrantFiled: November 18, 2012Date of Patent: March 24, 2015Assignee: International Business Machines CorporationInventors: Joy Cheng, Daniel J. Coady, Matthew E.
