title = "Better preparation of sol-gel Thin Film optical filter in presence of Surfactant",
abstract = "Preparation of sol-gel thin film was fabricated using spin-coating method. The preparation of a precursor containing tetraethylorthosilicate (TEOS) and Bismarck Brown Y (BBY) dye was prepared with different concentrations of sodium dodecyl sulfate (SDS) surfactant. Different concentrations of BBY were analyzed by measuring the absorbance using an Ocean Optics spectrometer. Its uniformity was examined under Axio Scope. A1 (ZEIZZ) microscope as well. After the best BBY concentrations were identified, different concentrations of SDS surfactant and their uniformity were analyzed. The presence of SDS in the sol-gel thin film improved repeatability of fluorophore (6-FAM) fluorescence measurements using CMOS sensor.",

note = "Funding Information: repeatability in both concentrations of BBY having lower RSD in 67% of the experiments performed. IV. FUTURE WORK Further optimization must be done for the filter, such as reduction of crack formation, uniformity and robustness. The addition of polydimethylsiloxane (PDMS-OH) [10] is a possible addition to precursor that could improve the cracking of the xerogel. Furthermore, to improve photodegradation of the film an amino group [11] would improve the performance for long-term measurements. Additionally, the implementation of these filters with different absorbance spectra in each pixel could be a breakthrough allowing the possibility to measure multi-analyte concentrations in parallel.
