Abstract
![]()
Detection of aerobic
marine bacterial biofilms using
electrochemical
impedance spectroscopy has been done to monitor the interfacial response
of Pseudoalteromonas sp. NCIMB 2021
attachment and growth in order to identify characteristic events on
a 0.2 mm diameter gold electrode surface. Uniquely, the applicability
of surface charge density has been proven to be valuable in determining
biofilm attachment and cell enumeration over a 72 h duration on a
gold surface within a modified continuous culture flow cell (a controlled
low laminar flow regime with Reynolds number ≈ 1). In addition,
biofilm dispersal has been evaluated using 500 nM sodium nitroprusside,
a nitric oxide donor (nitric oxide is important for the regulation
of several diverse biological processes). Ex situ confocal microscopy
studies have been performed to confirm biofilm coverage and morphology,
plus the determination and quantification of the nitric oxide biofilm
dispersal effects. Overall, the capability of the sensor to electrochemically
detect the presence of initial bacterial biofilm formation and extent
has been established and shown to have potential for real-time biofilm
monitoring.

Abstract
Reliable and accurate in situ sensors capable of detecting and quantifying troublesome marine biofilms on metallic surfaces are increasingly necessary. A 0.2 mm diameter gold electrochemical sensor was fully characterized using cyclic voltammetry in abiotic and biotic artificial seawater media within a continuous culture flow cell to detect the growth and development of an aerobic Pseudoalteromonas sp. biofilm. Deconvolution of the abiotic and biotic responses enable the constituent extracellular electron transfer and biofilm responses to be resolved. Differentiation of enhanced oxygen reduction kinetics within the aerobic bacterial biofilm is linked to enzyme and redox mediator activities.

Abstract
Microscopic imaging ellipsometry is an optical technique that uses an objective and sensing procedure to measure the ellipsometric parameters ? and ? in the form of microscopic maps. This technique is well known for being noninvasive and label-free. Therefore, it can be used to detect and characterize biological species without any impact. Microscopic imaging ellipsometry was used to measure the optical response of dried Streptococcus mutans cells on a glass substrate. The ellipsometric ? and ? maps were obtained with the Optrel Multiskop system for specular reflection in the visible range ( ? = 450 to 750 nm). The ? and ? images at 500, 600, and 700 nm were analyzed using three different theoretical models with single-bounce, two-bounce, and multibounce light paths to obtain the optical constants and height distribution. The obtained images of the optical constants show different aspects when comparing the single-bounce analysis with the two-bounce or multibounce analysis in detecting S. mutans samples. Furthermore, the height distributions estimated by two-bounce and multibounce analyses of S. mutans samples were in agreement with the thickness values measured by AFM, which implies that the two-bounce and multibounce analyses can provide information complementary to that obtained by a single-bounce light path.
