PublicationsOn the possibility of PhotoEmission Electron Microscopy for E.coli advanced studies
The novel approach was proposed for detailed high-resolution studies of morphology and physico-chemical properties concomitantly at one measurement spot of E.coli bacterial cells culture immobilized onto...
PublicationsCharacterization on Antibiotic Biocide Resistance Genes and Virulence Factors of Staphylococcus Species Associated with Bovine Mastitis in Rwanda
The present study was conducted from July to August 2018 on milk samples taken at dairy farms in the Northern Province and Kigali District of Rwanda in order to identify Staphylococcus spp. associated...
PublicationsMerging Top-Down and Bottom-Up Approaches to Fabricate Artificial Photonic Nanomaterials with a Deterministic Electric and Magnetic Response
Artificial photonic nanomaterials made from densely packed scatterers are frequently realized either by top-down or bottom-up techniques. While top-down techniques offer unprecedented control over achievable...
PublicationsSpatiotemporal Organization of Biofilm Matrix Revealed by Confocal Raman Mapping Integrated with Non-Negative Matrix Factorization Analysis
Biofilms are microbial aggregates of microorganisms surrounded by a hydrogel-like matrix formed by extracellular polymeric substances (EPS). The formation of biofilms is intrinsically complex, from the...
PublicationsCombined Raman and AFM detection of changes in HeLa cervical cancer cells induced by CeO2 nanoparticles – molecular and morphological perspectives
The design of nanoparticles for application in medical diagnostics and therapy requires a thorough understanding of various aspects of nanoparticle–cell interactions. In this work, two unconventional...
