Developing a transducer based on localized surface plasmon resonance (LSPR) of gold nanostructures for nanobiosensor applications
(Trans Tech Publications, 2013)In this work, we report the nanofabrication, optical characterization, and electromagnetic modeling of various nanostructure arrays for localized surface plasmon resonance (LSPR) based biosensing studies. Comparison of the ... -
Functional gold nanoparticle coated surfaces for CA 125 cancer biomarker detection
(TÜBİTAK, 2015)Here we describe the detailed characterization of gold nanoparticle (Au Np) functionalized surfaces as a biosensing platform by studying a model streptavidin (SA)–biotin interaction. Conjugation of SA on Au Np immobilized on ... -
Hybridization of fano and vibrational resonances in surface-enhanced infrared absorption spectroscopy of streptavidin monolayers on metamaterial substrates
(2014)We present spectral hybridization of organic and inorganic resonant materials and related bio-sensing mechanism. We utilized a bound protein (streptavidin) and a Fano-resonant metasurface to illustrate the concept. The ... -
Implantable microelectromechanical sensors for diagnostic monitoring and post-surgical prediction of bone fracture healing
(John Wiley and Sons Inc., 2015)The relationship between modern clinical diagnostic data, such as from radiographs or computed tomography, and the temporal biomechanical integrity of bone fracture healing has not been well-established. A diagnostic tool ... -
In situ synthesis of biomolecule encapsulated gold-cross-linked poly(ethylene glycol) nanocomposite as biosensing platform: A model study
(Elsevier BV, 2010)In situ synthesis of poly(ethylene glycol) (PEG) hydrogels containing gold nanoparticles(AuNPs) and glucose oxidase (GOx) enzyme by photo-induced electron transfer process was reported here and applied in electrochemical ... -
Nanofabrication and plasma polymerization assisted surface modification of a transducer based on localized surface plasmon resonance of gold nanostructure arrays for biosensor applications
(S P I E - International Society for Optical Engineering, 2012-07-31)The nanofabrication and surface modification of a transducer based on localized surface plasmon resonance (LSPR) of gold nanostructure arrays for biosensing was studied. We used electron beam lithography for the nanopatterning ... -
Nanogap based label-free impedimetric biosensors
(Bilkent University, 2012)Despite lots of research going on to find a hope, cancer is still a major cause of death in today‘s world. It has been reported that cancer has some biomarkers in human body and detecting these biomarkers timely can pave ... -
Plasmonic nanoparticle based nanobiosensors and nanophotodetectors
(SPIE, 2013)Plasmonics mainly deals with light-matter interactions in metallic nanostructures. It has gathered interest since its discovery due to the benefits it provides when compared with photonics and electronics. It owes its ... -
Recent advances in microneedle-based sensors for sampling, diagnosis and monitoring of chronic diseases
(MDPI AG, 2021-08-25)Chronic diseases (CDs) are noncommunicable illnesses with long-term symptoms accounting for ~70% of all deaths worldwide. For the diagnosis and prognosis of CDs, accurate biomarker detection is essential. Currently, the ... -
SILVER nano-cylinders designed by EBL used as label free LSPR nano-biosensors
(SPIE, 2011)Localized Surface Plasmon Resonance (LSPR) is based on the electromagnetic-field enhancement of metallic nano-particles. It is observed at the metal-dielectric interface and the resonance wavelength can be tuned by the ... -
Turn-on fluorescent dopamine sensing based on in situ formation of visible light emitting polydopamine nanoparticles
(American Chemical Society, 2014)Dopamine is the principle biomarker for diseases such as schizophrenia, Huntington's, and Parkinson's, and the need is urgent for rapid and sensitive detection methods for diagnosis and monitoring of such diseases. In this ...
