A novel carbohydrate antigen 125 electrochemical sensor based on sweet almond oil organo-hydrogels

Nahit AKTAŞ

Ovarian cancer is a gynecological disease causing many deaths among women around the world. Carbohydrate antigen 125 (CA-125) is a single biomarker known to be a tumor marker of ovarian cancer. CA-125 is widely used to monitor the treatment process, recurrences, and for the detection of ovarian cancer. Herein, organo-hydrogels were prepared in order to detect CA-125 sensitively in serum medium with electrochemical methods. Organo-hydrogels were obtained by the free radical polymerization reaction using agar and glycerol with varying proportions of sweet almond oil using methylene bisacrylamide ...More

Novel Cacao oil-based organo-hydrogels to detect carcinoma antigen 125 in serum medium; synthesis, characterization, and electrochemical measurements

Nahit AKTAŞ

In present study, cacao oil-based organo-hydrogels (OHCOs) are synthesized to detect carcinoma antigen 125 (CA-125) in serum medium with electrochemical methods such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and differential pulse voltammetry (DPV). OHCOs are prepared by the free radical polymerization reaction with agar, glycerol, and distinct ratios of cacao oil with glutaraldehyde (GA) crosslinker or methylene bisacrylamide (MBA) crosslinker. OHCOs are characterized via Fourier Transform Infrared Spec-troscopy (FT-IR), in different solvent environments and pH ...More

Nanostructured electrochemical cysteine sensor based on carbon nanotube supported Ru, Pd, and Pt catalysts

Nahit AKTAŞ

At present, a voltammetric L-Cystein (Cys) sensor is developed based on carbon nanotube (MWCNT) supported Ru, Pd, and Pt monometallic catalyst modified glassy carbon electrodes (GCE). Ru/MWCNT, Pd/MWCNT, and Pt/MWCNT catalysts are prepared via sodium borohydride reduction method and characterized with advanced surface analytical techniques as inductively coupled plasma mass spectrometry (ICP-MS), N2 adsorption-desorption, X-ray diffraction (XRD), and transission electron microscopy (TEM). Characterization results reveal that these catalysts are succesfully sythesized at desired metal loadings. ...More

Characterization of p(PmO), p(LO) and p(RO) organoparticles, their bioactivity properties and their effect on pancreatic cancer Capan-1 cell

Nahit AKTAŞ

For the first time in the literature, p (PmO), p (LO) and p (RO) organo-particles were synthesized from Peppermint oil, Lemon oil and Rose oil. Of the organo-particles L-929 cell line viability/cytotoxicity and anticancer effect against Capan-1 pancreatic cancer cell line were investigated. p (PmO), p (LO) and p (RO) organo-particles were featured by thermogravimetry (TGA), Fourier Transform Infrared Spectroscopy (FTIR), Scanning electron microscope (SEM), Particle size (DLS), and particle charge (zeta potential, Zeta) analyses. Antioxidant, biocompatible, and antimicrobial activities and in v ...More
