Arrays of indefinitely long uniform nanowires and nanotubes
(Nature Publishing Group, 2011)Nanowires are arguably the most studied nanomaterial model to make functional devices and arrays. Although there is remarkable maturity in the chemical synthesis of complex nanowire structures, their integration and ... -
Colorimetric detection of ultrathin dielectrics on strong interference coatings
(OSA - The Optical Society, 2018)Metal films covered with ultrathin lossy dielectrics can exhibit strong interference effects manifested as the broad absorption of the incident light resulting in distinct surface colors. Despite their simple bilayer ... -
Impact of mesoporous silica nanoparticle surface functionality on hemolytic activity, thrombogenicity and non-specific protein adsorption
(Royal Society of Chemistry, 2013)Although numerous mesoporous silica nanoparticle (MSN) drug carriers and theranostic agents with various surface functionalities have been designed in the last decade, their biocompatibility remains a matter of intensive ... -
Label-free optical biodetection of pathogen virulence factors in complex media using microtoroids with multifunctional surface functionality
(American Chemical Society, 2018)Early detection of pathogens or their virulence factors in complex media has a key role in early diagnosis and treatment of many diseases. Nanomolar and selective detection of Exotoxin A, which is a virulence factor secreted ... -
Macroscopic assembly of indefinitely long and parallel nanowires into large area photodetection circuitry
(American Chemical Society, 2012)Integration of nanowires into functional devices with high yields and good reliability turned out to be a lot more challenging and proved to be a critical issue obstructing the wide application of nanowire-based devices ... -
A new route for fabricating on-chip chalcogenide microcavity resonator arrays
(Wiley-VCH Verlag, 2014-07)High-yield production and on-chip integration of high-Q chalcogenide microresonators with various sizes and geometrical shapes (spherical, spheroidal, and ellipsoidal) and with sub-nanometer surface roughness is achieved. ... -
Oligonucleotide-based label-free detection with optical microresonators: strategies and challenges
(Royal Society of Chemistry, 2016)This review targets diversified oligonucleotide-based biodetection techniques, focusing on the use of microresonators of whispering gallery mode (WGM) type as optical biosensors mostly integrated with lab-on-a-chip systems. ... -
Phosphonate based organosilane modification of a simultaneously protein resistant and bioconjugable silica surface
(Royal Society of Chemistry, 2014)A facile method to coat silica surfaces with THPMP is introduced, forming simultaneously a protein resistant and bioconjugable surface. The coating is experimentally identified and its anti-fouling and bioconjugable ... -
Real-time and selective detection of single nucleotide DNA mutations using surface engineered microtoroids
(American Chemical Society, 2015)Mictoroids, as optical biosensors, can provide beneficial biosensing platforms to understand DNA alterations. These alterations could have significant clinical importance, such as the case of Pseudomonas aeruginosa, which ... -
Structural coloring in large scale core-shell nanowires
(American Chemical Society, 2011)We demonstrated two complementary size-dependent structural coloring mechanisms, interference and scattering, in indefinitely long core-shell nanowire arrays. The unusual nanostructures are comprised of an amorphous ... -
Thermally tunable ultrasensitive infrared absorption spectroscopy platforms based on thin phase-change films
(American Chemical Society, 2016-11)The thermal tunability of the optical and electrical properties of phase-change materials has enabled the decades-old rewritable optical data storage and the recently commercialized phase-change memory devices. Recently, ... -
Universal infrared absorption spectroscopy using uniform electromagnetic enhancement
(American Chemical Society, 2016)Infrared absorption spectroscopy has greatly benefited from the electromagnetic field enhancement offered by plasmonic surfaces. However, because of the localized nature of plasmonic fields, such field enhancements are ... -
Wafer-scale arrays of high-Q silica optical microcavities
(OSA - The Optical Society, 2017)On-chip high-Q microcavities possess significant potential in terms of integration of optical microresonators into functional optoelectronic devices that could be used in various applications, including biosensors, ...
