Antitumor activity of chitosan from mayfly with comparison to commercially available low, medium and high molecular weight chitosans
Tan, Gamze; Kaya, Murat; Tevlek, Atakan; Sargın, İdris; Baran, Talat (Springer, 2018)Insects' cuticles have a potential to be evaluated as a chitin source. Especially adults of aquatic insects like mayflies (order Ephemeroptera) swarm in enormous numbers in artificially lit areas while mating in spring and ... -
Cellular localization and biological effects of 20nm-gold nanoparticles
Tan, Gamze; Onur, Mehmet Ali (Wiley, 2018)Gold nanoparticles (AuNPs) have recently emerged as prominent vehicles for many biomedical applications from sensing to delivery. The relevant literature contains conflicting data about the effects of AuNPs on living cells. ... -
Chitosan nanofiber production from Drosophila by electrospinning
Kaya, Murat; Akyüz, Bahar; Bulut, Esra; Sargın, İdris; Eroğlu, Fatma; Tan, Gamze (Elsevier Science Bv, 2016)Drosophila melanogaster is one of the important test organisms in genetics thanks to its fast growth rate in a culture. This study demonstrates that the fly D. melanogaster can also be exploited as a source for nanofiber ... -
Comparison of garlic and onion extract-derived gold nanoparticles: Characterization and anticancer activity
Tan, Gamze; Tevlek, Atakan; Aydın, Halil Murat (Editions de Sante, 2023)The present study aims to probe the antioxidative and anticancer activities of gold nanoparticles (AuNPs) reduced by Allium cepa L. (onion-O) and Allium sativum L. (garlic-G) extracts. Versatile analyzes were employed to ... -
