    • Diagnosis of iron deficiency anemia using density-based fractionation of red blood cells 

      Hennek, Jonathan; Kumar, Ashok Ashwin; Wiltschko, Alexander Bame; Patton, Matthew Reiser; Lee, Si Yi Ryan; Brugnara, Carlo; Adams, Ryan Prescott; Whitesides, George McClelland (Royal Society of Chemistry (RSC), 2016)
      Iron deficiency anemia (IDA) is a nutritional disorder that impacts over one billion people worldwide, it causes permanent cognitive impairment in children, fatigue in adults, and suboptimal outcomes in pregnancy. IDA can ...

    • Evaluation of a Density-Based Rapid Diagnostic Test for Sickle Cell Disease in a Clinical Setting in Zambia 

      Kumar, Ashok A.; Chunda-Liyoka, Catherine; Hennek, Jonathan W.; Mantina, Hamakwa; Lee, S. Y. Ryan; Patton, Matthew R.; Sambo, Pauline; Sinyangwe, Silvester; Kankasa, Chipepo; Chintu, Chifumbe; Brugnara, Carlo; Stossel, Thomas P.; Whitesides, George M. (Public Library of Science, 2014)
      Although simple and low-cost interventions for sickle cell disease (SCD) exist in many developing countries, child mortality associated with SCD remains high, in part, because of the lack of access to diagnostic tests for ...

    • Fractionating Polymer Microspheres as Highly Accurate Density Standards 

      Bloxham, William Henry; Hennek, Jonathan; Kumar, Ashok Ashwin; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      This paper describes a method of isolating small, highly accurate density-standard beads and characterizing their densities using accurate and experimentally traceable techniques. Density standards have a variety of ...

    • From the Bench to the Field in Low-Cost Diagnostics: Two Case Studies 

      Kumar, Ashok Ashwin; Hennek, Jonathan; Smith, Barbara L; Kumar, Shailendra; Beattie, Patrick; Jain, Sidhartha; Rolland, Jason P.; Stossel, Thomas Peter; Chunda-Liyoka, Catherine; Whitesides, George McClelland (Wiley-Blackwell, 2015)
      Despite the growth of research in universities on point-of-care (POC) diagnostics for global health, most devices never leave the laboratory. The processes that move diagnostic technology from the laboratory to the field—the ...

    • A Paper-Based “Pop-up” Electrochemical Device for Analysis of Beta-Hydroxybutyrate 

      Wang, Chien-Chung; Hennek, Jonathan; Ainla, Alar; Kumar, Ashok Ashwin; Lan, Wen-Jie; Im, Judy S; Smith, Barbara S.; Zhao, Mengxia; Whitesides, George McClelland (American Chemical Society (ACS), 2016)
      This paper describes the design and fabrication of a “pop-up” electrochemical paper-based analytical device (pop-up-EPAD) to measure beta-hydroxybutyrate (BHB)—a key biomarker for diabetic ketoacidosis—using a commercial ...

    • 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 ...
