Optical Sensing of Microbial Life on Surfaces

Abstract: The label-free detection of microbial cells attached to a surface is an active field of research. The field is driven by the need to understand and control the growth of biofilms in a number of applications, including basic research in natural environments, industrial facilities, and clinical devices, to name a few. Despite significant progress in the ability to monitor the growth of biofilms and related living cells, the sensitivity and selectivity of such sensors are still a challenge. We believe that among … Show more

“…The formation of bio-films will be initiated by the attachment of proteins, followed by individual bacteria, which then trigger other microbial species to colonize. In Atlantic Ocean the bio-films are consist of bacteria, fungi, diatoms, protozoans, larvae, and algal spores embedded in an extracellular polymeric substance matrix [7]. The additional release of surfactants at the SML will be caused by more soluble organic components from the seaslicks and bio-films.…”

“…22,23 Surface plasmon resonance imaging (SPRi) has also been used experimentally for label free monitoring of biofilm formation on surfaces in real time 24,25 as have a variety of other optical techniques. 61 Although highly sensitive, these techniques still require device removal, are time consuming and necessitate multiple components, which incur high costs. Alternatively, non-invasive in vivo optical detection of biofilms in the human middle ear has been achieved using optical coherence tomography (OCT).…”

“…So far, biofilm sensing systems mainly based on optical and electrochemical transduction have been proposed. Optical devices encompassing optic fiber [29,30], surface plasmon [31], fluorescence methods [32] and others are based on the measurement of the increase in the layer thickness, the metabolic activity, the biofilm chemical composition and the presence of single chemical species [33]. Devices to monitor biofilm growth in situ have been designed, but their application has been mainly focused in the environmental and industrial area.…”
