Journal ArticleDOI
In-situ probe of gate dielectric-semiconductor interfacial order in organic transistors: origin and control of large performance sensitivities.
Stephanie R. Walter,Jangdae Youn,Jonathan D. Emery,Sumit Kewalramani,Jonathan W. Hennek,Michael J. Bedzyk,Antonio Facchetti,Tobin J. Marks,Franz M. Geiger +8 more
TL;DR: Surprisingly, the combined data reveal that while SAM molecular order dramatically impacts semiconductor crystalline domain size and carrier mobility, it does not significantly influence the local orientation of the overlying organic semiconductor molecules.
Journal ArticleDOI
DNA on stage: Showcasing oligonucleotides at surfaces and interfaces with second harmonic and vibrational sum frequency generation
TL;DR: In this paper, the authors survey how nonlinear optical probes access the electronic, vibrational, electrostatic, and chiral signatures of interfacial DNA in its native state and show how this exciting new field is directly applicable to tracking and understanding molecular recognition in DNA oligonucleotides and aptamers.
Journal ArticleDOI
Direct Probes of 4 nm Diameter Gold Nanoparticles Interacting with Supported Lipid Bilayers
Julianne M. Troiano,Laura L. Olenick,Thomas R. Kuech,Eric S. Melby,Dehong Hu,Samuel E. Lohse,Arielle C. Mensch,Merve Doğangün,Ariane M. Vartanian,Marco D. Torelli,Eseohi Ehimiaghe,Stephanie R. Walter,Li Fu,Christopher R. Anderton,Zihua Zhu,Hong-fei Wang,Galya Orr,Catherine J. Murphy,Robert J. Hamers,Joel A. Pedersen,Franz M. Geiger +20 more
TL;DR: In this paper, the authors present molecular-level investigations of how well-characterized silica-supported phospholipid bilayers formed from either pure DOPC or a 9:1 mixture of DOPc:DOTAP interact with positively and negatively charged 4 nm gold metal nanoparticles at pH 7.4 and NaCl concentrations ranging from 0.001 to 0.1 M.
Journal ArticleDOI
Ultra-sensitive protein detection via Single Molecule Arrays towards early stage cancer monitoring.
Stephanie M. Schubert,Lisa M. Arendt,Wenhui Zhou,Shazia Baig,Stephanie R. Walter,Rachel J. Buchsbaum,Charlotte Kuperwasser,David R. Walt +7 more
TL;DR: This work benchmarks the role of SiMoA as a vital tool in monitoring previously non-detectable protein biomarkers in serum for early cancer detection and offers significant potential as a non-invasive platform for the monitoring of early stage cancer.
Journal ArticleDOI

TL;DR: Results from experiments and computer simulations are reported that provide concrete lines of evidence for spontaneous lipid corona formation without active mixing upon attachment to stationary and suspended lipid bilayer membranes.
