Collagens are the most abundant protein in the animal kingdom. Collagens form the structural framework of connective tissues such as bones, tendons and skin and play important biomechanical role in supporting tissue functions. The preservation of collagen in deep time is a topic of intense debate. Here we provide indisputable evidence of the presence of collagen in Early Eocene fish vertebrae using online pyrolysis-comprehensive two dimensional gas chromatography-time-of-flight mass spectrometry and immunofluorescence studies. The presence...

Data from: Synthesis and characterization of silver nanoparticle-decorated cobalt nanocomposites (Co@AgNPs) and their density-dependent antibacterial activity

Magnetic cores loaded with metallic nanoparticles can be promising nano-carriers for successful drug delivery at infectious sites. We report fabrication, characteristic analysis and in vitro antibacterial performance of nanocomposites comprising of cobalt cores (Co-cores) functionalized with varied concentration of silver nanoparticles (AgNPs). A two-step polyol process synchronized with transmetallation reduction method was used. Co-cores were synthesized by cobalt acetate and decoration of AgNPs was carried out by silver acetate. The density of AgNPs was varied...
