In this study, we reported preparation and characterization of a new nano product consisting the combination two anti-inflammatory drugs: naproxen sulfasalazine (Sulfoxen) where both are currently used for treatment inflammatory disorders. The its structural were obtained by Fourier transform infrared (FT-IR) spectroscopy, X-ray powder diffraction (XRPD), Thermogravimetric analysis (TGA), Diffe...

Fundamental improvements in the design of Atomic Force Microscopy (AFM) components benefit a wide variety of applications such as AFM imaging and single molecule pulling. Trends towards high-speed AFM imaging require lower noise and higher bandwidth components, in particular the scanning unit, the force sensing cantilever and the AFM electronics, which also benefits low noise molecular measurem...

The unique ability of magnetotactic bacteria to navigate along a geomagnetic field is accomplished with the help of prokaryotic organelles, magnetosomes. The magnetosomes have well-ordered chain-like structures, comprising membrane-enveloped, nano-sized magnetic crystals, and various types of specifically associated proteins. In this study, we applied atomic force microscopy (AFM) to investigat...

The nanoManipulator system adds a virtual reality interface to an atomic force microscope (AFM), thus providing a tool that enables the user not only to image but also to manipulate nanometer-sized molecular structures. As the AFM tip scans the surface of these structures, the tip-sample interaction forces are monitored, which in turn provide information about the frictional, mechanical, and to...

PeakForce Quantitative Nanomechanical Mapping (QNM) is a new atomic force microscopy technique for measuring the Young’s modulus of materials with high spatial resolution and surface sensitivity, by probing at the nanoscale. In the present work, modulus results from PeakForceTM QNMTM using three different probes are presented for a number of different polymers with a range of Young’s moduli tha...

Polyhedral silsesquioxanes are considered valuable conjugation scaffolds. Nevertheless, only a few examples of silsesquioxane-assembled peptide oligomers have been reported to date. We developed a new bioorthogonal cube-octameric silsesquioxane (COSS) scaffold bearing eight aminooxy coupling sites allowing for the conjugation of diverse peptides via oxime ligation. We found that the coupling ef...

The high quality thin films of (CdS)0.6 Se0.4 have been synthesized using thermal evaporation technique onto precleaned rotating amorphous glass substrate at room temperature. The films were characterized by X-Ray Diffractometer, Scanning Electron Microscopy, Atomic Force Microscopy and UV-VIS Spectrophotometer. The XRD spectrum illustrates that the films are polycrystalline having hexagonal st...

Nanocrystalline zinc oxide thinfilms have been prepared on glass substrates at different temperatures through planar RF-magnetron sputtering. The particle size reduction with respect to substrate temperature has been studied with x-ray 144 K. Saravanakumar et al diffraction (XRD) and atomic force microscopy (AFM). Cross-sectional transmission electron microscopic (TEM) studies employing dark-fi...

Abstract Microelectromechanical system (MEMS) has been highly valued since the size of MEMS structure is miniaturized, spacing between components in nanometer range, and behaviors friction adhesion greatly affect reliability MEMS. An atomic force microscope (AFM) was used to observe surface morphology carbon nanotube (CNT)/polymethyl methacrylate (PMMA) film, X-ray photoelectron spectroscopy (X...
