En oncologie, les nanoparticules magnétiques sont utilisées pour brûler les cellules cancéreuses. Un nouvel usage, basé sur leur vibration au contact de ces cellules, est à l’étude par les chercheurs du CEA-Inac. Pour un traitement plus doux pour le patient, mais sans appel pour les tumeurs… Sources : Les DEFIS du CEA N°189, page 10 […]

En vibrant à leur contact sous l’effet d’un champ magnétique externe, des nanoparticules peuvent infliger à des cellules tumorales un stress mécanique fatal. Des physiciens de l’Inac ont élaboré et testé deux familles de nanoparticules. Leurs résultats confortent la perspective de thérapies ciblées contre le cancer. http://www-dsm.cea.fr/Phocea/Vie_de…  

Application of bio-functionalized magnetic micro-particles elaborated by the top-down approach Selma Leulmi is a PhD student at SPINTEC with background both in nanotechnology and biology who conducts the study on triggering cancer cell apoptosis. This particular project is currently explored at SPINTEC in collaboration with INAC/SPrAM and INAC/SCIB. Microparticles elaborated by the top-down approach are […]

The purpose of this WP is twofold. The first purpose is benchmark the performance of these CMOS/MTJ based circuits with those of CMOS-only circuits of similar functionalities. This work is still in progress but some initial results on CMOS/MTJ based microprocessor derived from RISK processor have already been obtained in WP4: Design of low-power hybrid […]

For the fabrication of CMOS/MTJ circuits, three different technological lines were developed and made accessible for HYMAGINE purposes. For simple circuits comprising only a few MTJs interconnected with CMOS transistors, the PTA 400m² upstream research clean-room located in SPINTEC building is used. A MRAM back-end process is operational at PTA and specific process steps required […]

Within HYMAGINE, circuits of increasing complexity have been conceived from simple non-volatile logic gates to microcontrollers or microprocessor. Below is an example of magnetic Look-Up-Table (MLUT) conceived within HYMAGINE and an example of hybrid CMOS/MTJmicroprocessor. Magnetic LUT for FPGA Our purpose was to develop a radiation-hardened FPGA based on MRAM. A FPGA (Field Programmable Gate […]

Thanks to their unique set of assets (non-volatility, speed, density, endurance), STT-MRAM are seen as a unique candidate for DRAM and/or Cache SRAM replacement allowing to drastically reduce the power consumption of electronic circuits thanks to new power gating strategies made possible by the non-volatility of these memories. For these applications, fast write speed (in […]
