Cryoprotectants are essential to prevent ice formation during tissue cryopreservation procedures. However, the control of their concentration and spatial distribution in the tissue is necessary to avoid toxicity and other damages associated with the cryopreservation procedures, especially for bulky samples such as tissues and organs. X-ray...
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disabling and chronic disease, importantly related to the current COVID-19 pandemic. Currently, there are no specific laboratory tests to directly diagnose ME/CFS. In this work, the use of impedance spectroscopy is studied as a potential technique for the diagnosis of ME/CFS. A...
In this work, a simple protocol based on electrical impedance measures is implemented to detect changes on chemical composition, the microstructure (percentage and size of pores) and the surface modification treatments of metallic implants. The Hewlett-Packard 4395A Agilent impedance analyzer was employed for these measurements. Discs of...
Three-dimensional printing technologies have been recently proposed to monitor cell cultures and implement cell bioreactors for di erent biological applications. In tissue engineering, the control of tissue formation is crucial to form tissue constructs of clinical relevance, and 3D printing technologies can also play an important role for this...
Criopreservación celular por vitrificación con bajas concentraciones de crioprotector.El objeto de la presente invención se refiere a un nuevo procedimiento de criopreservación celular, que consigue la vitrificación de las muestras biológicas con presenci
It is proposed a microscopy for cell culture applications based on impedance sensors. The imagined signals are measured with the Electrical Cell-Substrate Spectroscopy (ECIS) technique, by identifying the cell area. The proposed microscopy allows real-time monitoring inside the incubator, reducing the contamination risk by human manipulation....
