Welcome to the Institute of Microelectronics of Barcelona IMB-CNM-CSIC

The Barcelona Institute of Microelectronics (IMB-CNM), CSIC, is a well-positioned research center in the development of new Micro, Nano Technologies, Components and Systems. This center is a leader in the application of such technologies to solve social challenges and is aligned with the sustainable development objectives.

IMB-CNM research focuses on basic and applied research and development in micro and nanotechnologies, components and systems. Its lines of research include the entire value chain from the components of detection, power, and actuation, signal transmission and its application to the health and well-being of people, help control environmental conditions, and save and improve efficient management of energy.

Conferences will be held in Spanish from 10:00 to 10:45, moderated by researcher Eli Prats, with the participation of César Fernández, David Quirión and Roger Escudé.


Multidimensional Anisotropic Architectures on Polymeric Microparticles
J.P. Agusil, M.I. Arjona, M. Duch, N. Fusté, J.A. Plaza

Next generation technologies will require Multidimensional Anisotropic Architectures with tunable physical and chemical intraparticle building blocks combination to meet the demands of high throughput and multiplexing. Here, we report a strategy to integrate a vast number of anisotropic dimensions combining polymer photolithography with (bio)chemical modifications via soft lithography. Our work allows a combination of microparticle traits in a 15-dimensional anisotropic space at the micrometric scale. No current technology provides these degrees of physical, chemical, surface coverage, and surface pattern anisotropies, which can be used interchangeably or in combination; obtaining an innumerable number of engineering microparticles with barcoding capabilities.

Technological development of intracellular polysilicon-chromium-gold chips for orthogonal chemical functionalization
S. Durán et al.

Taking advantage of the ability of microelectronics to manufacture devices under cell dimensions and a large variety of features, we report a technology for the fabrication of multi-material chips as bi-functional cell-internalizable devices. These microtools have a promising future as intracellular functional platforms for biosensing, diagnosis and drug delivery.

Increasing the eleastic modulus of graphene by controlled defect creation
Guillermo López-Polín et al.

The presence of lattice defects in graphene might degrade its mechanical properties. We report a study on the elastic modulus and strength with a controlled density of defects. Counter-intuitively, the in-plane Young’s modulus increases with defect density up to 2x the initial value for a vacancy content of ~0.2%.
