    • Automating Microfluidics: Reconfigurable Virtual Channels for Cell and Droplet Transport 

      Floryan, Caspar Jerzy; Nemiroski, Alex; Westervelt, Robert M. (2012-07-17)
      The emerging field of digital microfluidics promises to solve many shortcomings of traditional continuous-flow fluidics. This technology has a few incarnations, including EWOD (eletrowetting on dielectric) and DEP ...
    • 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 ...
    • Camouflage and Display for Soft Machines 

      Morin, Stephen A.; Shepherd, Robert F.; Kwok, Sen Wai; Stokes, Adam A.; Nemiroski, Alex; Whitesides, George M. (American Association for the Advancement of Science (AAAS), 2012)
      Synthetic systems cannot easily mimic the color-changing abilities of animals such as cephalopods. Soft machines—machines fabricated from soft polymers and flexible reinforcing sheets—are rapidly increasing in functionality. ...
    • Engineering Shadows to Fabricate Optical Metasurfaces 

      Nemiroski, Alex; Gonidec, Mathieu; Fox, Jerome Michael; Jean-Remy, Philip; Turnage, Evan; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      Optical metasurfaces—patterned arrays of plasmonic nanoantennas that enable the precise manipulation of light–matter interactions—are emerging as critical components in many nanophotonic materials, including planar ...
    • An implantable wireless biosensor for the immediate detection of upper GI bleeding: a new fluorescein-based tool for diagnosis and surveillance (with video) 

      Ryou, Marvin K.; Nemiroski, Alex; Azagury, Dan; Shaikh, Sohail N.; Ryan, Michele B.; Westervelt, Robert M.; Thompson, Christopher C. (Elsevier BV, 2011)
      Background: Early recurrent hemorrhage after endoscopic intervention for acute upper GI bleeding (UGIB) can approach 20% and leads to increased morbidity and mortality. Little has changed over the past several decades ...
    • Noncontact orientation of objects in three-dimensional space using magnetic levitation 

      Subramaniam, A. B.; Yang, Dian; Yu, H.-D.; Nemiroski, Alex; Tricard, S.; Ellerbee, A. K.; Soh, S.; Whitesides, George McClelland (Proceedings of the National Academy of Sciences, 2014)
      This paper describes several noncontact methods of orienting objects in 3D space using Magnetic Levitation (MagLev). The methods use two permanent magnets arranged coaxially with like poles facing and a container containing ...
    • Tilted Magnetic Levitation Enables Measurement of the Complete Range of Densities of Materials with Low Magnetic Permeability 

      Nemiroski, Alex; Soh, Siowling; Kwok, Sen Wai; Yu, Hai-Dong; Whitesides, George McClelland (American Chemical Society (ACS), 2016)
      Magnetic levitation (MagLev) of diamagnetic or weakly paramagnetic materials suspended in a paramagnetic solution in a magnetic field gradient provides a simple method to measure the density of small samples of solids or ...
    • 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 ...
    • Using Magnetic Levitation for Non-Destructive Quality Control of Plastic Parts 

      Hennek, Jonathan; Nemiroski, Alex; Subramaniam, Anand; Bwambok, David K.; Yang, Dian; Harburg, Daniel V.; Tricard, Simon; Ellerbee, Audrey K.; Whitesides, George McClelland (Wiley-Blackwell, 2015)
      Magnetic levitation (MagLev) enables rapid and non-destructive quality control of plastic parts. The feasibility of MagLev as a method to: i) rapidly assess injection-molded plastic parts for defects during process ...
