Microfluidic bubble logic
(Massachusetts Institute of Technology, 2008)In this thesis, I propose a new paradigm in computing where bits can simultaneously transport and manipulate materials and information. Information representation is invariably physical. Though this insight is fundamental ... -
Microfluidic cell culture chambers with nanoporous walls for chemical communication
(Massachusetts Institute of Technology, 2013)Reconstruction of phylogenetic trees based on 16S rRNA gene sequencing reveals that so far only a tiny fraction of microbial diversity has been cultured in the laboratory. One major reason behind this "unculturability" is ... -
Microfluidic concentration-enhanced single cell enzyme activity assay
(Massachusetts Institute of Technology, 2013)Cells sense stimuli, process information and respond using signaling networks regulated by enzymatic activity of various proteins. Aberrations in signaling are associated with diseases such as cancer. Most current methods ... -
Microfluidic devices for analysis of red blood cell mechanical properties
(Massachusetts Institute of Technology, 2010)Decreased deformability of human red blood cells (RBCs) is both a cause of disease and biomarker for disease (1). To traverse blood capillaries, the biconcave disk-shaped RBC must deform dramatically, since the diameter ... -
