Publication number: 20130338044Abstract: A bifunctional linker and method of use is provided that has a spacer molecule with a functional group on one end configured to couple to the surface of a substrate and a function group on the other end that is configured couple to a biomolecule and methods of use. The preferred bifunctional linker has a poly(ethylene glycol) spacer ranging from 3 to 20 ethylene glycol units that has a silane functional group to react with a substrate and an azide functional group that can couple to a biomolecule that includes an alkyne group. The preferred linker can produce an azide-derivatized glass surface in one step and the azide functional group of the spacer can in sequence conjugate with a biomolecule using click chemistry, which can be conducted at low temperature and in aqueous solution.Type: ApplicationFiled: June 10, 2013Publication date: December 19, 2013Inventors: Jiayu Liao, Yongfeng Zheng

Publication number: 20130324439Abstract: A combinatorial elastic modulus-modified microenvironment microarray (eMEArray) platform and methods for cell-based functional screening of interactions with combinatorial microenvironments. The platform and methods allow for simultaneous control of the molecular composition and the elastic modulus, and combines the use of microarray and micropatterning technologies. The eMEArrays have been used to show that the microenvironment has effects on drug-cell interactions and contributes to therapeutic response.Type: ApplicationFiled: June 5, 2013Publication date: December 5, 2013Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Mark A. LaBarge, Chun-Han Lin

Publication number: 20130288919Abstract: A system and method for electrically detecting a target material in a sample without the need for labeling is described. A probe supporting member defining at least one hole is functionalized with target specific probe material and a change in the hole area on binding of target material is detected as a change in an ionic current through the hole. In some embodiments, an electro-chemical cell comprising an electrode having a conducting layer and a porous insulating layer is provided. In some embodiments, an electrically addressable array is provided for detection of a potentially large number of target materials in a sample.Type: ApplicationFiled: June 21, 2013Publication date: October 31, 2013Inventor: Mino Green
