New post - Effective gamma-ray sterilization and characterization of conductive polypyrrole biomaterials (https://www.nanoworld.com/blog/effective-gamma-ray-sterilization-and-characterization-of-conductive-polypyrrole-biomaterials/?utm_source=Google%2B&utm_medium=Blog&utm_content=Effective+gamma-ray+sterilization+and+characterization+of+conductive+polypyrrole+biomaterials&utm_campaign=NanoWorld+Blog) has been published on NanoWorld Blog.

"Conductive polymers, including polypyrrole (PPy), have been extensively explored to fabricate electrically conductive biomaterials for bioelectrodes and tissue engineering scaffolds. For their in vivo uses, a sterilization method without severe impairment of original material properties and performance is necessary. Gamma-ray radiation has been commonly applied for sterilization of medical products because of its simple and uniform sterilization without heat generation.[...]"*

In the article “Effective gamma-ray sterilization and characterization of conductive polypyrrole biomaterials” by Semin Kim et. al cited here, the authors describe the first study on gamma-ray sterilization of PPy bioelectrodes and its effects on their characteristics.

The surface topography and roughness of the PPy and γ-PPy electrodes were analyzed by atomic force microscopy. The experiments were performed using a NanoWorld Pointprobe® NCHR AFM probe https://www.nanoworld.com/pointprobe-tapping-mode-reflex-coated-afm-tip-nchr . All images were acquired at a 0.3 Hz scan rate in tapping mode.

New interesting publication " A fibrin biofilm covers blood clots and protects from microbial invasion" by Macrea et. al mentioning the use of NANOSENSORS uniqprobe qp-BioAC https://www.nanosensors.com/uniqprobe-uniform-quality-spm-probe-contact-or-dynamic-mode-for-Biology-in-dynamic-AC-mode-qp-BioAC :

““Hemostasis requires conversion of fibrinogen to fibrin fibers that generate a characteristic network, interact with blood cells, and initiate tissue repair. The fibrin network is porous and highly permeable, but the spatial arrangement of the external clot face is unknown. Here we show that fibrin transitioned to the blood-air interface through Langmuir film formation, producing a protective film confining clots in human and mouse models. We demonstrated that only fibrin is required for formation of the film, and that it occurred in vitro and in vivo. The fibrin film connected to the underlying clot network through tethering fibers. It was digested by plasmin, and formation of the film was prevented with surfactants. Functionally, the film retained blood cells and protected against penetration by bacterial pathogens in a murine model of dermal infection. Our data show a remarkable aspect of blood clotting in which fibrin forms a protective film covering the external surface of the clot, defending the organism against microbial invasion.”*

New post - Direct AFM-based nanoscale mapping and tomography of open-circuit voltages for photovoltaics (https://www.nanoworld.com/blog/direct-afm-based-nanoscale-mapping-and-tomography-of-open-circuit-voltages-for-photovoltaics/?utm_source=Google%2B&utm_medium=Blog&utm_content=Direct+AFM-based+nanoscale+mapping+and+tomography+of+open-circuit+voltages+for+photovoltaics&utm_campaign=NanoWorld+Blog) has been published on NanoWorld Blog.

In the article cited below Katherine Atamanuk, Justin Luria and Bryan D. Huey present "a new approach for directly mapping VOC (open-circuit voltage) with nanoscale resolution, requiring a single, standard-speed AFM scan. This leverages the concept of the proportional-integral-derivative (PID) feedback loop that underpins nearly all AFM topography imaging."*

NanoWorld™ CDT-NCHR conductive diamond coated silicon AFM probes were used in the described CT-AFM experiment. https://www.nanoworld.com/pointprobe-conductive-diamond-coated-tapping-mode-afm-tip-cdt-nchr

“Cadmium Telluride (CdTe) is an inexpensive thin-film photovoltaic with ca. 5% of the 2017 global market share for solar cells. To optimize the efficiency and reliability of these, or any electronic devices, a thorough understanding of their composition, microstructure, and performance is necessary as a function of device design, processing, and in-service conditions. Atomic force microscopy (AFM) has been a valuable tool for such characterization, especially of materials properties and device performance at the nanoscale. In the case of thin-film solar cells, local photovoltaic (PV) properties such as the open-circuit voltage, photocurrent, and work function have been demonstrated to vary by an order of magnitude, or more, within tens of nanometers […]"
