Plasmon-coupled photocapacitor neuromodulators
(American Chemical Society, 2020)
Efficient transduction of optical energy to bioelectrical stimuli is an important goal for effective communication with biological systems. For that, plasmonics has a significant potential via boosting the light−matter ...
Chemical funneling of colloidal gold nanoparticles on printed arrays of end-grafted polymers for plasmonic applications
(American Chemical Society, 2020-06)
Spatially defined assembly of colloidal metallic nanoparticles is necessary for fabrication of plasmonic devices. In this study, we demonstrate high-resolution additive jet printing of end-functional polymers to serve as ...
Large scale compatible fabrication of gold capped titanium dioxide nanoantennas using a shadowing effect for photoelectrochemical water splitting
(Elsevier, 2020)
In this paper, a visible light driven plasmonic based photoelectrochemical water splitting (PEC-WS) cell is designed with an elegant two-step fabrication route. First, titanium dioxide (TiO2) nanowires (NWs) were synthesized ...
Highly efficient semiconductor-based metasurface for photoelectrochemical water splitting: broadband light perfect absorption with dimensions smaller than the diffusion length
(Springer, 2020)
In this paper, we demonstrate a highly efficient light trapping design that is made of a metal-oxide-semiconductor-semiconductor (nanograting/nanopatch) (MOSSg/p) four-layer design to absorb light in a broad wavelength ...
Fabrication of flexible, cost-effective, and scalable silver substrates for efficient surface enhanced Raman spectroscopy based trace detection
(Elsevier BV, 2021-06-20)
The fabrication and optimization of cost-effective, eco-friendly, uniform and flexible SERS platforms by facile synthesis routes has recently attracted great attention for trace detection of various analytes. Herein, we ...
Ultra-broadband near-unity light absorption by disjunct scattering resonances of disordered nanounits created with atomic scale shadowing effect
(Springer, 2020)
Metamaterial perfect absorbers have been the subject of many studies in recent years. Near-unity light harvesting in an ultra-broadband frequency range is the prime goal in many applications such as photoconversion systems. ...
Strong light–matter interactions in Au plasmonic nanoantennas coupled with Prussian blue catalyst on BiVO4 for photoelectrochemical water splitting
(Wiley-VCH Verlag, 2020)
A facial and large‐scale compatible fabrication route is established, affording a high‐performance heterogeneous plasmonic‐based photoelectrode for water oxidation that incorporates a CoFe–Prussian blue analog (PBA) structure ...
SERS-active linear barcodes by microfluidic-assisted patterning
(Elsevier, 2020-09-28)
Simple, low-cost, robust, and scalable fabrication of microscopic linear barcodes with high levels of complexity and multiple authentication layers is critical for emerging applications in information security and ...
Physically unclonable surfaces via dewetting of polymer thin films
(American Chemical Society, 2021-03-10)
From anti-counterfeiting to biotechnology applications, there is a strong demand for encoded surfaces with multiple security layers that are prepared by stochastic processes and are adaptable to deterministic fabrication ...
