Journal ArticleDOI
Colorimetric detection of DNA sequences based on electrostatic interactions with unmodified gold nanoparticles
Huixiang Li,Lewis J. Rothberg +1 more
TL;DR: It is found that single- and double-stranded oligonucleotides have different propensities to adsorb on gold nanoparticles in colloidal solution and this observation is used to design a hybridization assay based on color changes associated with gold aggregation.
Journal ArticleDOI
Label-Free Colorimetric Detection of Specific Sequences in Genomic DNA Amplified by the Polymerase Chain Reaction
Huixiang Li,Lewis J. Rothberg +1 more
TL;DR: It is documented that single-stranded DNA adsorbs on negatively charged gold nanoparticles (Au-nps) with a rate that depends on sequence length and temperature, which forms the basis for a colorimetric assay to identify specific sequences and single nucleotide polymorphisms on polymerase chain reaction (PCR)-amplified DNA.
Journal ArticleDOI
New Phases of C60 Synthesized at High Pressure
Yoshihiro Iwasa,Taka-hisa Arima,R. M. Fleming,Theo Siegrist,Otto Zhou,Robert C. Haddon,Lewis J. Rothberg,K.B. Lyons,H. L. Carter,Arthur F. Hebard,Robert Tycko,Gary Dabbagh,J. J. Krajewski,Gordon A. Thomas,Takehiko Yagi +14 more
TL;DR: Infrared, Raman, and nuclear magnetic resonance studies show a drastic reduction of icosahedral symmetry, as might occur if the C60 molecules are linked, in accord with the reduced solubility of the pressure-induced phases.
Journal ArticleDOI
Electronic structure and photoexcited-carrier dynamics in nanometer-size CdSe clusters.
M. G. Bawendi,William L. Wilson,Lewis J. Rothberg,P. J. Carroll,T. M. Jedju,Michael L. Steigerwald,Louis E. Brus +6 more
TL;DR: The band-gap luminescence is not from the exciton state, but from a surface trapped state and results in long-lived bleach and induced-absorption features in pump-probe experiments.
Journal ArticleDOI
Defect quenching of conjugated polymer luminescence.
TL;DR: In this article, the structure of these defects is studied by vibrational spectroscopy and the reason they act as quenchers is explained, and the new picture of photoexcitations which emerges and its implications for polymer electroluminescent devices are discussed.
