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…
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…
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…
