Experimental plasmonic sensing of malaria using an aluminum metasurface
A. S. Kiyumbi, M. S. Tame
A wide range of methods currently exist for testing the presence of malaria, each with its own advantages and disadvantages. New technologies are urgently needed to develop more ef…
A divergent-beam surface plasmon resonance architecture for multiplexed malaria biosensing
Amos. S. Kiyumbi, Jordan. H. Hossea
We present a numerical study of a divergent-beam Kretschmann surface plasmon resonance (SPR) platform for multiplexed malaria biosensing. A Powell-lens-generated angular fan enable…
Trifolium nanocavity metasurfaces on single-crystal Au(111) for depth-tunable optical-variable reflection
Amos Sospeter Kiyumbi
Symmetry-broken plasmonic nanocavities provide a simple route to engineer reflective optical response in continuous-metal metasurfaces. Here, we report an experimental study of tri…
Circular V-grooves on single-crystal gold: optical properties and sensing feasibility
Amos Sospeter Kiyumbi
Single-crystal Au(111) microplates provide an ultra-smooth, low-defect platform for reproducible plasmonic nanocavities. Here we realize reflection-mode whispering-gallery metasurf…
An effective microscopic model for plasmonic sensing of malaria
A. S. Kiyumbi, M. S. Tame
Malaria remains a major health threat in low-resource regions and rapid diagnostic tests often lack the sensitivity required for early detection. To address this and help establish…
