    • Analytical Devices Based on Direct Synthesis of DNA on Paper 

      Glavan, Ana C; Niu, Jia; Chen, Zhen; Güder, Firat; Cheng, Chao-Min; Liu, David Ruchien; Whitesides, George McClelland (American Chemical Society (ACS), 2016)
      This paper addresses a growing need in clinical diagnostics for parallel, multiplex analysis of biomarkers from small biological samples. It describes a new procedure for assembling microarrays of ssDNA and proteins on ...
    • Chemical Approaches to the Surface Engineering of Paper and Cellulose-Based Materials for Microfluidics, Electronics and Low-Cost Diagnostics 

      Glavan, Ana (2016-01-27)
      Paper (and other cellulose-based materials such as cotton thread and fabrics) are underexploited as materials for the construction of “high-tech” and “lab-on-a-chip” devices. One major drawback of paper is its tendency to ...
    • Electroanalytical devices with pins and thread 

      Glavan, Ana C; Ainla, Alar; Hamedi, Mahiar Max; Fernández-Abedul, M. Teresa; Whitesides, George McClelland (Royal Society of Chemistry (RSC), 2016)
      This work describes the adaptive use of conventional stainless steel pins—used in unmodified form or coated with carbon paste—as working, counter, and quasi-reference electrodes in electrochemical devices fabricated using ...
    • Folding Analytical Devices for Electrochemical ELISA in Hydrophobic R H Paper 

      Glavan, Ana C; Christodouleas, Dionysios; Mosadegh, Bobak; Yu, Hai Dong; Smith, Barbara S.; Lessing, Joshua; Fernández-Abedul, M. Teresa; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      This work describes a device for electrochemical enzyme-linked immunosorbent assay (ELISA) designed for low-resource settings and diagnostics at the point of care. The device is fabricated entirely in hydrophobic paper, ...
    • Inkjet Printing of Conductive Inks with High Lateral Resolution on Omniphobic “R F Paper” for Paper-Based Electronics and MEMS 

      Lessing, Joshua; Glavan, Ana C; Walker, S. Brett; Keplinger, Christoph; Lewis, Jennifer; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      The use of omniphobic “fluoroalkylated paper” as a substrate for inkjet printing of aqueous inks that are the precursors of electrically conductive patterns is described. By controlling the surface chemistry of the paper, ...
    • Omniphobic “R F Paper” Produced by Silanization of Paper with Fluoroalkyltrichlorosilanes 

      Glavan, Ana C; Martinez, Ramses; Subramaniam, Anand; Yoon, Hyo; Nunes, Rui M. D.; Lange, Heiko; Thuo, Martin M.; Whitesides, George McClelland (Wiley-Blackwell, 2013)
      The fabrication and properties of “fluoroalkylated paper” (“\(R^F\) paper”) by vapor-phase silanization of paper with fluoroalkyl trichlorosilanes is reported. \(R^F\) paper is both hydrophobic and oleophobic: it repels ...
    • Paper-Based Electrical Respiration Sensor 

      Guder, Firat; Ainla, Alar; Redston, Julia; Mosadegh, Bobak; Glavan, Ana C; Martin, T. J.; Whitesides, George McClelland (Wiley-Blackwell, 2016)
      Current methods of monitoring breathing require cumbersome, inconvenient, and often expensive devices; this requirement sets practical limitations on the frequency and duration of measurements. This article describes a ...
    • Rapid fabrication of pressure-driven open-channel microfluidic devices in omniphobic RF paper 

      Glavan, Ana Cristina; Martinez, Ramses V.; Maxwell, E. Jane; Bala Subramaniam, Anand Bala; Nunes, Rui M. D.; Soh, Siowling; Whitesides, George McClelland (Royal Society of Chemistry (RSC), 2013)
      This paper describes the fabrication of pressure-driven, open-channel microfluidic systems with lateral dimensions of 45-300 microns carved in omniphobic paper using a craft-cutting tool. Vapor phase silanization with a ...
    • Soft Actuators and Robots that Are Resistant to Mechanical Damage 

      Martinez, Ramses; Glavan, Ana C; Keplinger, Christoph; Oyetibo, Alexis I.; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      This paper characterizes the ability of soft pneumatic actuators and robots to resist mechanical insults that would irreversibly damage or destroy hard robotic systems—systems fabricated in metals and structural polymers, ...
