XI International Workshop on Sensors and Molecular Recognition: System for detection of senescent cells in vivo

The XI International Workshop on Sensors and Molecular Recognition will take place on 6 and 7 July 2017 at the Polytechnic University of Valencia. Scientists of the unit 26 of NANBIOSIS will present the results of the research carried on together with researchers from the Universitat Politècnica de València, CNIO, CIBER-BBN and the University of Cambridge: an innovative system that allows the detection of senescent cells in vivo and without damaging the tissue. The main objective of cellular senescence is to prevent the proliferation of damaged cells and, at the same time, to trigger tissue repair. However, when the damag[...]

Nanoparticles capable of bi-directional communication

The results of a research co-led by Ramón Martínez-Máñez, Scientific Director of Unit 26 of NANBIOSIS and CIBER-BBN have been published by Nature Communication last May 30th, showing how to prepare a nanoparticles chemical communication system using lactose. So far, his group had managed to establish communication between three nanoparticles but only in a unidirectional way. “We have managed to get a nanoparticle to send a chemical messenger to the second nanoparticle, who understands the message and sends another chemical messenger back to the first one. Upon receiving it, it performs an action, in this case releasing a dye,” explains[...]

Electronic tongues for detecting prostate and bladder cancer

Researchers of the Applied Molecular Chemistry Group, coordinator of Unit 26 of NANBIOSIS, have participated in the development of a new low-cost system for non-invasive diagnosis of prostate and bladder cancer. It consists of a device of electronic tongues ​​based on metal electrodes, which makes it possible to quickly and easily detect this pathology from a urine sample. The researchers evaluated the efficacy of this system from the analysis of urine samples from patients before and after surgery. In addition, samples were collected from patients with benign prostatic hyperplasia, integrated into the non-cancer group for the study of prostate cancer.[...]

New sensor for quick and easy detection of ecstasy

Spanish, Danes and Austrian researchers, including the group led by Ramón Martínez Mánez, coordinator of Unit 26 of NANBIOSIS, have developed a new sensor to detect ecstasy in a simple, reliable, fast and selective way. Until now, this drug is detected by techniques such as capillary electrophoresis, spectroscopy or chromatography that require the use of expensive technical equipment and qualified personnel. The new method offers the advantages of easy use, low cost and high reliability according to Beatriz Lozano, a researcher at the Interuniversity Institute for Research on Molecular Recognition and Technological Development at the Universitat Politècnica de València and[...]

Laboratory-scale prototype for the treatment of cutaneous tumours

Ramon Martínez Máñez, Scientific Director of Unit 26 of NANBIOSIS, has participated in the development, on a laboratory scale, of a low cost device for treatments based on the application of optical hyperthermia by laser. Among the applications of this technique are the therapies against cutaneous cancer and its objective is to get the death of the tumour cells by overheating. Overheating is achieved by the irradiation of synthesized metal nanoparticles. The prototype developed consists of an infrared laser with a power of up to 500mW able to provide a power density of up to 4W / cm2, a sensor[...]

U 26 NANBIOSIS - New implants for the treatment of infections and bone tumours
New implants for the treatment of infections and bone tumours

Researchers of Unit 26 of NANBIOSIS participate in the design and evaluation of the cellular level of a new hybrid material for the creation of intelligent-scaffolds implants that open the door to a more efficient treatment of infections and bone tumors. The main novelty is the incorporation of a mesoporous matrix of silicon, calcium and phosphorus oxides, with molecular gates that would allow the controlled release of substances stored inside the pores, such as antitumor drugs or antibiotics. A molecular gate is a mechanism whose opening depends on certain external stimuli, in this particular case the drugs would only b[...]

Ramón Martínez, Scientific Director of Unit 26 of NANBIOSIS Co-leads the development of nanodevices to detect the presence of cocaine

Researchers of the Universitat Politècnica de València (UPV), the Universitat Rovira i Virgili (URV) and CIBER of Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) have developed new nanodevices to detect the presence of cocaine in saliva or in any another aqueous solution. Part of the characterization of the probe was carried out using NMR facilities from NANBIOSIS. The paper is published in the journal Scientific Reports, of the group Nature. The development consists of a molecular gate designed with nanoporous alumina, an aluminum oxide prepared by electrochemical means with pores of micrometric diameter. “A molecular gate -explains Ramón Martínez-Máñez, scientific director of[...]

Three Universities among the 200 best in the world in science, hosting 4 Units of NANBIOSIS.
4 Units of NANBIOSIS hosted in three Universities among the 200 best in the world in science.

The University of Zaragoza is one of the 200 best universities in the world in science research, according to the latest Shanghai ranking of 2016 in a specific analysis by macro areas. In order to elaborate this ranking by macroareas indicators such as the number of students and professors who have obtained the Nobel prize or Fields medal, the number of researchers highly cited in the scientific literature, the number of scientific articles indexed in the Science Citation Index and the Percentage of articles published in the most cited 20% scientific journals are used. Only six Spanish universities are among[...]
