Electrochemical sensors for cortisol detections: Almost there

Researchers of NANBIOSIS Unit 8 Micro– Nano Technology Unit at the Microelectronic Institute of Barcelona, (of IMB-CNM, CSIC / CIBER-BBN) has recently published a review in the TrAC Trends in Analytical Chemistry entitled “Electrochemical sensors for cortisol detections: Almost there” highlighting:

Overview of electrochemical techniques for cortisol detection published in the last five years.

Recent advances in cortisol detection by electrochemical immunoassays.

Potential of biosensing techniques for cortisol detection in biological matrices.

Importance of cortisol quantification for clinical applications.

Abstract

Mostly known as “the stress hormone”, cortisol has many essential functions in humans due to its involvement in regulation of blood pressure, immune system, metabolism of protein, carbohydrate, adipose, and anti-inflammatory action. Since a right cortisol balance is essential for human health, many efforts are currently being made to monitor the cortisol level in the human body. Cortisol levels are usually monitored in blood, plasma, serum, oral fluid, sweat, and hair samples through immunochemical and analytical methods, but in the last decade, electrochemical measurements are proving to be reliable techniques for cortisol quantification in biological matrices with the advantages of a fast response by portable and wearable devices. This review gathers the most recent developments and works on electrochemical sensors for cortisol detection, highlighting their high technology maturity and potential for clinical applications.

Guillem Vargas Nadal, researcher at Nanomol Group – NANBIOSIS U6 (ICMAB-CSIC and CIBER-BBN) and Nanomol Technologies will defend his PhD thesis on Friday, 23 October 2020, at 11 am in an online session. The PhD Thesis Defense will be held by videoconference from the ICMAB Meeting Room.

Further information and Registration to attend the PhD Thesis defense via Zoom nanoparticles at ICMAB-website.

Supervisors:

Nora Ventosa (Scientific Director of NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit and leader of Nanomol Group of CIBER-BBN
Lidia Ferrer (Nanomol Technologies S.L.)

Abstract: The nanovesicles are being developed and investigated to be used in the pharmaceutical world to deliver drug and detect diseases. However, there are some drawbacks related to the nanovesicles that must be considered, like their stability and their applicability. Concerning that, in this Thesis we have developed a new type of stable nanovesicles called MKC-Quatsomes to be used as intravenous drug delivery systems. Their production, physicochemical characteristics, and stability are strongly related to the dispersant medium. Furthermore, the MKC-Quatsomes were labeled with fluorescent organic dyes, which present FRET phenomenon in order to overcome the drawbacks of the single-dye-loaded nanoparticles.

New test trials to diagnose Covid 19: Ramon Martinez, Scientific Director of CIBER-BBN is interviewed by Spanish Television

Ramón Martinez, Scientific Director of CIBER-BBN and NANBIOSIS unit 26 NMR: Biomedical Applications II is interviewed by Spanish Television about the research he is coordinating at the Polytechnic University of Valencia to develop new tests as an alternative to PCR.

Dr. Elena Aznar CIBER researcher at IQMA-IDM-UPV group explains how work these test that allow to diagnose quickly, easily, reliably and cheaply if a person is or has been infected by the SARS-COV-2 virus. Ramón Martínez Máñez, leader of the project, reports on the point where the investigation is, as well as the difference of these tests with PCR or antigen tests. These tests implement a technology of the research group that has already been used for other pathogens and that they try to adapt to the COVID virus. “My impression – explains Dr. Martínez – is that the time will come when these tests can be sold in pharmacies and can be used by the users themselves. At the moment we have to see if they work in patient samples and then adapt it so that be a marketable kit by an interested company “

Impact of Extracellular Vesicle Isolation Methods on Downstream miRNA Analysis in Semen

An article by Sara Larriba of the Human Molecular Genetics Group of Bellvitge Biomedical Research Institute (IDIBELL), recently published by the International Journal of Molecular Science. entitled “Impact of Extracellular Vesicle Isolation Methods on Downstream miRNA Analysis in Semen: A Comparative Study“, acknowledges NANBIOSIS ICTS for its participation in the research results. The nanoparticle tracking analysis was performed by the ICTS NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit.

Abstract:

Seminal plasma (SP) contains a unique concentration of miRNA, mostly contained in small extracellular vesicles (sEVs) such as exosomes, some of which could be clinically useful for diagnosis and/or prognosis of urogenital diseases such as prostate cancer (PCa). We optimized several exosome-EV isolation technologies for their use in semen, evaluating EV purifying effectiveness and impact on the downstream analysis of miRNAs against results from the standard ultracentrifugation (UC) method to implement the use of SP sEV_miRNAs as noninvasive biomarkers for PCa. Our results evidenced that commercial kits designed to isolate exosomes/EVs from blood or urine are mostly applicable to SP, but showed quantitative and qualitative variability between them. ExoGAG 3500× g and the miRCURY Cell/Urine/CSF 1500× g methods resulted as equivalent alternative procedures to UC for isolating exosomes/sEVs from semen for nanoparticle characteristics and quality of RNA contained in vesicles. Additionally, the expression profile of the altered semen sEV-miRNAs in PCa varies depending on the EV isolation method applied. This is possibly due to different extraction techniques yielding different proportions of sEV subtypes. This is evidence that the exosome-EV isolation method has a significant impact on the analysis of the miRNAs contained within, with important consequences for their use as clinical biomarkers. Therefore, miRNA analysis results for EVs cannot be directly extrapolated between different EV isolation methods until clear markers for delineation between microvesicles and exosomes are established. However, EV extraction methodology affects combined models (semen exosome miRNA signatures plus blood Prostate specific antigen (PSA) concentration for PCa diagnosis) less; specifically our previously described (miR-142-3p + miR-142-5p + miR-223-3p + PSA) model functions as molecular marker from EVs from any of the three isolation methods, potentially improving the efficiency of PSA PCa diagnosis..

Nanoprobes for the next generation of Optical Imaging

Judit Morlà Folch, CIBER-BBN Researcher in Nanomol Group and NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit at ICMAB-CSIC is giving the seminar “Nanoprobes for the next generation of Optical Imaging“, today Monday, 5 October 2020 at 12 pm, Hosted by Nora Ventosa, Nanomol Group in the cycle of Online ICMAB PostDoc Talk.

Online Invited Seminar by Zoom. Register here to attend.

About the Seminar: Molecular imaging plays a vital role in the healthcare sector, since abnormal conditions and diseases are often diagnosed through imaging, while therapeutics methods used for the treatment of the abnormalities are often guided by imaging. Optical imaging is a highly sensitive technique and low-cost procedure in comparison to tomography, Magnetic Resonance Imaging (MRI) or ultrasounds among the other forms of imaging currently employed. Among the imaging agents, fluorescent organic nanoparticles (FONs) are emerging as an attractive alternative to the well-established fluorescent inorganic nanoparticles or small organic dyes. Their proper design allows one to obtain biocompatible probes with superior brightness and high photostability, although usually affected by low colloidal stability

Judit Morlà Folch began her postdoc in 2008 at New Jersey Institute of Technology (NJIT, EEUU) under the Marie Curie Tecniospring and Postdoctoral Programme in collaboration with ICMAB-CSIC (Nanomol Group), where she is nowadays working on the development of fluorescent organic nanoparticles for bioimaging.
