Plasmonic photothermal response of a phantom embedded with gold nanorod aggregates on broadband near-infrared irradiation
Dheeraj Pratap, Rizul Gautam, Amit Kumar Shaw +2
Longer near-infrared wavelengths provide better penetration depth in biological tissues, so these are useful for plasmonic photothermal cancer therapeutics. In the context of nanop…
Experimental observation of Berreman modes in uniaxial anisotropic nanoporous alumina film on aluminium substrate
Dheeraj Pratap, Jitendra Kumar Pradhan, Subramanium Anantha Ramakrishna
In this article, we demonstrate experimentally and verified numerically the excitation of Berreman modes that propagate in a dielectric film of uniaxial anisotropic nanoporous alum…
Photothermal properties of stable aggregates of gold nanorods
Dheeraj Pratap, Vikas, Rizul Gautam +2
Aggregation of the nanoparticles is a natural phenomena due to various biological and physical parameters but these aggregates are highly unstable. If aggregates would have been st…
Photothermal effects in small gold nanorod aggregates for therapeutic applications
Dheeraj Pratap, Ram Krishna Shah, Sameer Khandekar +1
Proximity of the metal nanoparticles enhance the plasmonic coupling and shifts the resonance. This article presents a numerical study of the photothermal effect in aggregates of sm…
Nanoporous alumina microtubes for metamaterial and plasmonic applications
Dheeraj Pratap, S. Anantha Ramakrishna
Double anodization of aluminium microwires in an acid bath yields cylindrical nanoporous alumina with nonbranching radially emanating pores. The obtained nanoporous alumina is a cy…
Effect of air confinement on thermal contact resistance in nanoscale heat transfer
Dheeraj Pratap, Rakibul Islam, Patricia Al-Alam +2
We report herein the pressure dependent thermal contact resistance (Rc) between Wollaston wire thermal probe and samples which is evaluated within the framework of an analytical mo…
Anisotropic Metamaterial Optical Fibers
Dheeraj Pratap, S. Anantha Ramakrishna, Justin G. Pollock +1
Internal physical structure can drastically modify the properties of waveguides: photonic crystal fibers are able to confine light inside a hollow air core by Bragg scattering from…
