IMB-CNM talks: Alternative materials for bio-sensing: silk fibroin from Bombyx mori - Augusto Márquez

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
11/05/2018 11:30 a.m.

Abstract: The field of commercial point of care (POC) tests for glucose monitoring in blood is widely covered with the glucose test strips for electrochemical measuring. Colorimetric analysis in this case is poor developed, while in other preliminary tests (pH, pregnancy, lead acetate) is commonly used. This aspect is logic as blood has a strong red color due to the presence of hemoglobin, what suppose an important interference. To prevent this drawback, cellulose is commonly employed to filter the sample, but also to manage the fluidics and retain the interactive elements (i.e. lateral flow tests). In this talk, I will present silk fibroin as an alternative to cellulose. This material covers in great part paper functionalities like capillary pumping and filtering but also and present others: i) mechanical properties: possibility to develop thin film biosensors resistant to mechanical stress, ii) biocompatibility: possibility to encapsulate biomolecules without disturbing their activity and also to be implanted in patients, iii) enzyme activity sustainer: the crystalline structure may isolate the immobilized biomolecules from harmful agents, iv) waveguide: besides acting as a biocompatible matrix, the silk fibroin can guide the light in a biosensor, being transparent in the visible and iv) compatibility with micro and nanofabrication technology (stamping, e-beam).

IMB-CNM talks: Keeping Moore’s law alive: block copolymer lithography - Steven Gottlieb

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
20/04/2018 11:30 a.m.

Abstract: The use of block copolymers for lithography applications has attracted significant attention in the last years because it is an interesting bottom-up technique that enables patterning with a resolution in the range from 5 to 25 nm. Block copolymer thin film spin-coating and annealing leads to a microphase separation process which, however, lacks the capability of inducing long-range order in the system. Lithographically defined features – mostly defined by top-down methods – capable of ordering the block copolymer domains on large length scales are referred to as guiding patterns. Besides a brief introduction to block copolymer physics we explain why block copolymer lithography is a possible technique for future node semiconductor manufacturing. An emphasis is on explaining the need for the fabrication of guiding patterns to direct the self-assembly of block copolymers. The second part of this presentation is about recent results in the fabrication of guiding patterns to direct the block copolymer self-assembly in lithographically relevant structures. These results include the use of extreme ultraviolet interference lithography (EUV-IL), electron beam lithography and thermal scanning probe lithography (t-SPL). Most of the presented results have been obtained within the framework of the European infrastructure project NFFA (Nanoscience Foundries and Fine Analysis), where the CNM is, among others, active in the sub-area “High-precision manufacturing”.

IMB-CNM talks: Microphysiological systems for modeling and monitoring biological barriers - Jose Yeste, IMB-CNM.

Sala de Actos Pepe Millán, IMB-CNM, Campus UAB.
06/04/2018 11:30 a.m.

Abstract: Epithelia and endothelia delineate tissue compartments and control their environments by regulating the passage of ion and solutes. This barrier function is essential for the development and maintenance of multicellular organisms, and its dysfunction is associated with numerous human diseases. Recent advances in biomaterials and microfabrication technologies have evolved in vitro approaches for modeling biological barriers. Current microphysiological systems have become more efficient and reliable in mimicking the native cell microenvironment and are promising tools for basic research, toxicology, and disease modeling. In this talk, I will describe some microfluidic cell cultures developed in our group for modeling and monitoring biological barriers, including the renal epithelial tubule and the blood-retinal barrier.
