Information Processing in Chemical Sensing: Unified Evolution Coding by Stretched Exponential

Gold surface cleaning by etching polishing: Optimization of polycrystalline film topography and surface functionality for biosensing

“…For recording and processing of the contact angle measurements, KSV instrument CAM 101 (www.biolinscientific.com) with KSV CAM 200 software was used, for the -processing of AFM images -Gwyddion (Department of Nanometrology, Czech Metrology Institute), UV-VIS -InSight software (Thermo Scientific, Germany), electrochemistry -NOVA 2.1.2 software (Metrohm, www.metrohm.com) (Metrohm Autolab B. V. Utrecht, The Netherlands), SPR spectroscopy -Biosuplar-510 (www.biosuplar.de). SPR kinetics G(t) were analyzed with a model that takes heterogeneous processes on the surface into account using a stretched exponential function [67][68][69]: (1) where N is the response range, τ is the time scale coefficient, and β is the parameter that indicates the mechanism of the surface layer evolution. The procedures of OriginPro 7.5 (OriginLab Corporation) were used for the fitting.…”

“…1), reflecting an improved surface homogeneity. This result can be easily understood in the framework of the Central limit theorems governing the mathematical statistics of such distributions [67][68][69]: after processing in Piranha, the Cauchy distribution (Lorentzian curve) implies that the surface profile contains peaks and valleys of any size leading to the so-called heavy tails of distribution. After processing in HAHP, the resulting Gaussian distribution of the height indicates that the elements of surface roughness have all approximately the same size range.…”

“…9). As shown in [21,43,[51][52][53][54][109][110][111], this approach allows elucidation of the mechanism underpinning the dominant surface process within the framework of the most common nonequilibrium dynamics model to date [5,67,68]. The data were obtained for the kinetic curve sections starting from 3.5 minute after the beginning of the sample injection, when stable HSA concentration in the cell is achieved.…”

“…are negative and constitute from 50 to 100% of the dark response ( Table 2). The nature of the decay of TAE of the illumination power is the same for different samples and is well described by the function of a stretched exponent specific for the environments with nano-microdimensional topological non-ordering [35,36]: ( )…”
