ILMS of cross-linked gelatin/chitosan blends have been successfully synthesized using glutaraldehyde as a cross-linker. The synthesized samples were characterized using infrared Fourier transformation (FT-IR), and X-ray diffraction (XRD). The solubility in aqueous media, the pH-responsive swelling and point of zero surface charge were explored. The adsorption efficiency of samples for the removal of the anionic dye aniline blue from aqueous media has been studied. The parameters that affect the adsorption efficiency as pH, initial dye concentration, contact time and temperature have been examined. Kinetics studies showed that the adsorption process was well described by the pseudo-second-order model and the equilibrium adsorption results fitted Freundlich model. Fitting the experimental data with Dubinin-Radushkevich model indicated a predominant physisorption mechanism. The maximum dye removal achieved by 1:1 gelatin/chitosan at pH 5 and 35°C was 99.8%. The activation energy for the adsorption process increases as the chitosan content increases which indicating chemisorption behavior. Thermodynamic studies indicated that the adsorption is spontaneous, endothermic in nature and results in higher entropy.

This dissertation describes the development of liquid biopsy using the signals of cancer stem cells (CSCs) in blood as a standalone diagnostic modality. Considering the complexity of cancer, it is necessary to capture the tumour-heterogeneity for robust diagnosis. Current state of the art with non-invasive methods relying on imaging has many limitations such as low sensitivity, inability to identify recurrent tumor or discrimination between primary or metastatic tumors. Since imaging-based diagnosis fails to provide sufficient specificity, tissue biopsyremainstobe thegoldstandardfordefinitive diagnosis. However, tissuebiopsyishighlyinvasive and can only provide a snapshot of the tumor, failing to capture the dynamic tumor landscape. Therefore, new tools are urgently required for accurate tracking of tumor dynamics to enhance cancer prognosis. Liquidbiopsy (LB) can serve as a routine, minimally invasive clinical tool for accurate diagnosis of cancer. Although, the circulating biomarkers in LB better represent the tumor heterogeneity, while being economical and easily applicable in clinical setting for practical patient care; existing LB faces many challenges with pre-analytical preprocessing of biomarkers resulting in biomarker degradation, poor diagnostic accuracy, and long turnaround time. To overcome the existing barriers of LB, I have developed an ultrasensitive sensor for the detection of rare signals of CSC associated bioactive material in circulation. I initiated this research by design and optimization of miniature sized (sub 10 nm) probes for in-vitro biological applications. Next, I employed CSCs-based diagnostic approach because CSCs demonstrate unique characteristics such as self-renewal, tumor initiation, differentiation, and propagation. Prediction of CSC fate by revealing the trajectory of cancer prognosis was undertaken for the first time. Lastly, I demonstrated that the probes, were capable of detection of cancer directly from plasma without extraction or purification of biomarkers. The simplicity of sample processing retainsthe authenticityofcirculatingtumor content,minimizing the source oferrors.The quantum probe platform can provide results in about 60 minutes after blood withdrawal from patients. This diagnostic modality was validated with conventional assays. In this dissertation, CSC associated circulating biomarkers for liquid biopsy are developed,advancing the modality towardsclinical translation.

“…The textile industry uses acid, basic, direct, and azo dyes (13). In this study, we tested the biodegradation of Congo red (a direct dye), methylene blue (a basic dye), and aniline blue (an azo dye) because they are representative of compound structures in each group and are commonly used in the textile industry as well as other studies on biodegradation (Figure 1, [14][15][16]. To summarize, this study aims to determine whether the fungi can decolorize the dyes and provide a new method to reuse fungi disposed by the fungi industry and biodegrade textile pollution.…”

Properly disposing of wastewater-containing textile dyes has long been a problem for the textile industry. An innovative method, biodegradation, can degrade certain dyes more efficiently and in a more environmentally-friendly method than the commonly used physicochemical treatments. Fungus is one of the materials capable of biodegradation without requiring further processing. In this study, we tested the edible fungi, Lentinula edodes, Pleurotus eryngii, and Pleurotus ostreatus, to see if they can used for a biodegradation of dyes. The textile dyes were applied into the suspension of these fungi for a biodegradation test, and the absorbance changes were recorded. After a reaction of one and a half hours, aniline blue dye and Congo red dye demonstrate the greatest degradation, reaching a biodegradation rate of 67.39–67.5% and 58.1–63.2%, respectively. Even the methylene blue dye that had the lowest degradation reached a biodegradation rate of 24.7–33.6%. These results show the fungi’s capability to decolorize the dyes, presenting a potential method for biodegrading textile pollution and the possibility of using natural products to reduce polluted wastewater.
