Article Title: Fiber‐Optic SERS Probes Fabricated Using Two‐Photon Polymerization For Rapid Detection of Bacteria

doi: 10.1002/adom.201901934

Figure Lengend Snippet: Figure 6. Results from demonstration of rapid detection of live E. coli in suspension. a) Four representative spectra obtained from HSVA on planar substrate. The highlighted regions in grey indicate where SERS peaks commonly appeared. b–e) Raw spectra (b,d) of background taken in PBS solution (dashed line) and E. coli suspension in PBS (solid line) from a representative CSA-SOT, and baseline corrected spectra (c,e) from multiple CSA-SOTs averaged over 100 spectra collected with 1 s (b,c) and 10 s (d,e) integration times.

Article Snippet: To characterize the sensing capabilities at different concentrations, and to ascertain the LOD, serial dilutions were performed to produce R6G solutions with concentrations ranging from 10−3 m down to 10−15 m. Bacteria Sample Preparation: Non-pathogenic E. coli K12 J53-1 (ATCC BAA-769, ATCC, USA) were cultured in autoclaved tryptic soy broth (Sigma–Aldrich, Germany) at 37 °C overnight with agitation.

Techniques: Suspension

Bacteriostatic activity in natural SPA waters with different abiotic components and a spring drinkable water with low mi- neral content (BLM): E. coli survival after 24 h of incubation at 37 °C. As additional controls were used 0.9% Saline Solution (SS) and Phosphate Buffer Saline (PBS). Values of CFUs are normalized on the t0 value and data are expressed as percentage of survival. Mean value and standard deviation of ex- periments in triplicate.

Figure Lengend Snippet: Fig. 3. Increment of the native antibacterial activity by TiO2 treatment. Experimental test with high mi- neral content water (W3, sulphate bicarbonate water containing alkaline hearth metals) after contamina- tion with E. coli and treatment with TiO2 nano- particles. Data were expressed as survival percen- tages of E. coli bacteria after exposition to dark, ultraviolet (UV) and white colour light at visible wavelengths. Data collected at different times of exposition: blue bars before TiO2 exposition, orange bars at 1 h and grey bars after 5 h of TiO2 exposition.

Data were expressed as means of CFU x 102 count on agar plates incubation after 120 min exposure (T120) at several wavelengths of the visible spectrum. Starting E. coli concentration at T0: < 105 (A) and > 105 (B). (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
