    • Adaptive Use of Bubble Wrap for Storing Liquid Samples and Performing Analytical Assays 

      Bwambok, David K.; Christodouleas, Dionysios; Morin, Stephen A.; Lange, Heiko; Phillips, Scott T.; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      This paper demonstrates that the gas-filled compartments in the packing material commonly called “bubble wrap” can be repurposed in resource-limited regions as containers to store liquid samples, and to perform bioanalyses. ...
    • Broadly Available Imaging Devices Enable High-Quality Low-Cost Photometry 

      Christodouleas, Dionysios; Nemiroski, Alex; Kumar, Ashok Ashwin; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      This paper demonstrates that, for applications in resource-limited environments, expensive microplate spectrophotometers that are used in many central laboratories for parallel measurement of absorbance of samples can be ...
    • Electrically Activated Paper Actuators 

      Hamedi, Mahiar; Campbell, Victoria; Rothemund, Philipp Josef Michael; Guder, Firat; Christodouleas, Dionysios; Bloch, Jean-Francis; Whitesides, George McClelland (Wiley-Blackwell, 2016)
      This paper describes the design and fabrication of electrically controlled paper actuators that operate based on the dimensional changes that occur in paper when the moisture absorbed on the surface of the cellulose fibers ...
    • 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, ...
    • Integrating Electronics and Microfluidics on Paper 

      Hamedi, Mahiar; Ainla, Alar; Guder, Firat; Christodouleas, Dionysios; Fernández-Abedul, M. Teresa; Whitesides, George McClelland (Wiley-Blackwell, 2016)
      The fields of paper microfluidics and printed electronics have developed independently, and are incompatible in many of their aspects (e.g. printed electronic thin films are not designed to tolerate the flows of liquids, ...
    • Polymerization-based Signal Amplification for Paper-Based Immunoassays 

      Badu-Tawiah, Abraham K.; Lathwal, Shefali; Kaastrup, Kaja; Al-Sayah, Mohammad; Christodouleas, Dionysios; Smith, Barbara L; Whitesides, George McClelland; Sikes, Hadley D. (Royal Society of Chemistry (RSC), 2015)
      Diagnostic tests in resource-limited settings require technologies that are affordable and easy to use with minimal infrastructure. Colorimetric detection methods that produce results that are readable by eye, without ...
    • Universal mobile electrochemical detector designed for use in resource-limited applications 

      Nemiroski, Alex; Christodouleas, Dionysios; Hennek, J. W.; Kumar, Ashok Ashwin; Maxwell, E. J.; Fernandez-Abedul, M. T.; Whitesides, George McClelland (Proceedings of the National Academy of Sciences, 2014)
      This paper describes an inexpensive, handheld device that couples the most common forms of electrochemical analysis directly to “the cloud” using any mobile phone, for use in resource-limited settings. The device is designed ...
