Melanoma is one type of skin cancer that develops from melanocytes and has been reported as the cause of deaths in different continents globally. This study aims to selectively "kill" only skin cancer cells by applying a customer designed and portable atmospheric pressure plasma jet (APPJ). Human melanoma (A375) and Lewis lung carcinoma (LLC) were selected as the target cancer cells to compare with the effects of APPJ toward L-929 mouse fibroblasts. The impacts of APPJ treatments on the cell viability and morphology of three types of cells were evaluated quantitatively by LDH and MTT assays whereas the qualitative cell behavior was provided by cell morphological changes. Importantly, the mechanism of evolution in cell fate resulted from APPJ treatments for the three types of cells was elucidated by cell apoptosis integrated with caspase-9 activities, which determined the threshold of APPJ treatment time toward individual cell type. Furthermore, it was found that the cell culture time assisted benign cells (L-929 fibroblasts) to resume proliferation activities from the impact of APPJ treatment. Therefore, the selective impacts on tumor and benign cells demonstrated in this study shed lights of APPJ treatments for the future developments of direct plasma skin cancer therapy.

“…Microbial or bacterial cellulose possesses the same monomer characteristics as plant cellulose, however, a lower degree of polymerisation and a microcrystalline structure, as well as a higher degree of purity set it apart from conventional cellulose (Jonas and Farah, 1998). BC membranes also do not need a deprotection step and are nevertheless quite similar to RC membranes in their reactivity, which was exploited by Kurniawan et al (Kurniawan et al, 2013). They synthesised mPEG-IPDI from monofunctional methyl ether PEG and IPDI, which was then subsequently coupled with the BC membrane surface.…”

Bacterial cellulose (BC) is a homopolymer and it is distinguished from plant-based cellulose by its unique properties such as high purity, high crystallinity, high water-holding capacity, and good biocompatibility. Microalgae are unicellular, photosynthetic microorganisms and are known to have high protein, starch, and oil content. In this study, Chlorella vulgaris was evaluated as source of glucose for the production of BC. To increase the starch content of algae the effect of nutrient starvation (nitrogen and sulfur) and light deficiency were tested in a batch assay. The starch contents (%) were 5.27 ± 0.04, 7.14 ± 0.18, 5.00 ± 0.08, and 1.35 ± 0.04 for normal cultivation, nitrogen starvation, sulfur starvation, and dark cultivation conditions, respectively. The performance of enzymatic and acidic methods was compared for the starch hydrolysis. This study demonstrated for the first time that acid hydrolysate of algal starch can be used to substitute glucose in the fermentation medium of Komagataeibacter hansenii for BC production. Glucose was used as a control for BC production. BC production yields on dry weight basis were 1.104 ± 0.002 g/L and 1.202 ± 0.005 g/L from algae-based glucose and glucose, respectively. The characterization of both BCs produced from glucose and algae-based glucose was investigated by scanning electron microscopy and Fourier transform infrared spectroscopy. The results have shown that the structural characteristics of algae-based BC were comparable to those of glucose-based BC.
