Description

Located at the Research Center onNanoscience and Nanotechnology(CIN2), CSIC, at the campus of Universidad Autónoma de Barcelona (UAB) the Biodeposition Unit consists of a versatile and automated molecular printer that can dispense minute volumes of solutions (from atto to femtoliter volumes) on a wide variety of surfaces to create user-defined patterns of spots or lines with high spatial resolution. The system is suitable for the functionalization of biosensors with any kind of biomolecule, nanoparticles, graphene or other nanostructures,for surface patterning for cell culture, or for the preparation of micro/nanoarrays, among other applications. The laboratory also harbors a Surface Plasmon Resonance (SPR) service. The Unit is coordinated by Prof. LauraM. Lechuga, group leader from the Nanobiosensorsand Bioanalytical Applications Group (nanoB2A) at CIN2-CSIC.

New methodology for cancer screening paves the way for more targeted treatment options

Laura Lechuga, Scientific Director of Unit 4 of NANBIOSIS, is co-author of a new paper published in Scientific Reports. According to Cesar Huertas, co-author of the article, the Gene expression is the process by which information from a gene is converted into a functional product, such as a protein. It is controlled by a complex regulatory network wherein diverse cellular mechanisms enable the cell to respond to its ever-changing environment. One such mechanism is alternative splicing (AS) of mRNA precursors, a particularly flexible regulatory control point where diverse protein isoforms of differing, even opposing, functions are generated. However, these regulation[...]

Laura Lechuga in the fight against cancer

Dr. Laura Lechuga, Scientific Director of Unit 4 of NANBIOSIS is highlighted in Cinco Días. Elpais Economía  for its fight against cancer and, in particular, for the device developed with its team to detect the disease in matter of minutes “Have you ever wondered why glucose meters are so smart that they just measure sugar? The answer is that they carry specific proteins that only interact with sugar, “explains the doctor.  The same idea lies in the device designed by Laura Lechuga and her research group “With a minimum sample of the patient, it is possible to detect the presenc[...]

A multiplexing nanophotonic biosensor for cancer diagnosis
A multiplexing nanophotonic biosensor for cancer diagnosis

The group Biosensors and bio-analytic applications, led by Laura Lechuga,​ coordinator of Unit 4 of NANBIOSIS, has developed a methodology through a nano-photonic sensor (known as bimodal waveguide interferometer) capable of quantifying, directly and mark-free, the different messenger RNA isoforms generated by alternative splicing. The expertise in biodeposition and biodetection systems of Lechuga’s group has permitted a thorough analytical study and optimization of the methodology, achieving not only total selectivity, but also excellent levels of sensitivity and reproducibility, and obtaining the lowest levels of detection in direct detection of messenger RNA isoforms generated by this mechanism without the need for PCR amplification (polymerase chain reaction). T[...]

Nanotechnology bio applications in the clinical diagnosis II: biosensor BiMW for the early diagnosis of bacterial infections in cirrhotic patients

The peritonitis bacterial spontaneous is an infection of the fluid ascetic that has high incidence in cirrhotic patients and is associated with a high mortality. In such situation, a diagnosis early is essential for the survival of the patient. However, the identification of the causative pathogen of infection is based currently on cultivation methods that are slow and laborious. A research coordinated by the Group of Nanobiosensors and Bioanalytical applications of the CIBER-BBN, which coordinates Unit 4 of NANBIOSIS led by Laura Lechuga, has presented the development of a biosensor interferometric based in guides bimodal (BiMW), capable of identify and[...]

Nanotechnology bio applications in the clinical diagnosis: nanoplasmodic biosensor device for the early diagnosis of colorectal cancer

The group of Nano-biosensors and Bioanalytical applications of CIBER-BBN which coordinates Unit 4 of NANBIOSIS directed by Dr. Laura Lechuga, has led the final preparations of a technology with potential application in the early diagnosis of colorectal cancer, based in the detection of specific biomarkers in blood. The nanoplasmonic biosensor based on LSPR (Localized Surface Plasmon Resonance) is generated on structured surfaces of nano discs of gold, that allow monitoring of biological interactions in real time and without the need of markers. The nanoplasmonic biosensor allows analysis of human samples in a few minutes, without requiring reagents or additional instrumentation.[...]
