  • Encapsulation Technology to Protect Probiotic Bacteria
    Probiotics, 2012
    Co-Authors: Maria Chavarri, Izaskun Maranon, María Del Carmen
    Abstract:

    Probiotic bacteria are used in production of functional foods and pharmaceutical products. They play an important role in promoting and maintaining human health. In order, to produce health benefits probiotic strains should be present in a viable form at a suitable level during the product is shelf life until consumption and maintain high viability throughout the gastrointestinal tract. Many reports indicated that there is poor survival of probiotic bacteria in products containing free probiotic cells [1]. Providing probiotic living cells with a physical barrier to resist adverse environmental conditions is therefore an approach currently receiving considerable interest [2]. The Encapsulation techniques for protection of bacterial cells have resulted in greatly enhanced viability of these microorganisms in food products as well as in the gastrointestinal tract. Encapsulation is a process to entrap active agents within a carrier material and it is a useful tool to improve living cells into foods, to protect [3, 4, 5, 6, 7], to extend their storage life and to convert them into a powder form for convenient use [8, 9, 10, 11]. In addition, Encapsulation can promote controlled release and optimize delivery to the site of action, thereby potentiating the efficacy of the respective probiotic strain. This process can also prevent these microorganisms from multiplying in food that would otherwise change their sensory characteristics. Otherwise, materials used for design of protective shell of encapsulates must be food-grade, biodegradable and able to form a barrier between the internal phase and its surroundings.

  • thin film Encapsulation Technology for harms using sacrificial cf polymer
    Sensors and Actuators A-physical, 2008
    Co-Authors: Danny Reuter, Andreas Bertz, M Nowack, Thomas Gessner
    Abstract:

    Abstract This paper reports on a new method for thin film Encapsulation of microelectromechanical systems (MEMS) using plasma enhanced chemical vapor deposited (PECVD) fluorocarbon polymer as sacrificial material and a stress optimized SiO/SiN/Al capping layer. Because of the oxygen plasma-based removal of the sacrificial organic layer, this technique is applicable for a wide range of MEMS technologies—from surface to high aspect ratio microstructures. It saves die area compared with bonding techniques and enables standard packaging processes such as dicing, pick and place and plastic injection molding. Beside of the fabrication Technology, we present results of the finite element analysis (FEA) regarding the deflection and the mechanical stress in the cap. The results of the FEA have been verified on fabricated structures by interferometric measurements.

  • Robust hermetic wafer level thin-film Encapsulation Technology for stacked MEMS / IC package
    2008 58th Electronic Components and Technology Conference, 2008
    Co-Authors: Y. Shimooka, M. Inoue, M. Endo, S. Obata, A. Kojima, T. Miyagi, Y. Sugizaki, I. Mori, H. Shibata
    Abstract:

    This paper reports a thin-film Encapsulation Technology for wafer level micro-electro-mechanical systems (MEMS) package, using poly-benzo-oxazole (PBO) sacrificial material and plasma enhanced chemical vapor deposited silicon oxide (PECVD SiO) cap layer. This technique, which is applicable for MEMS technologies, saves die size and enables conventional package processes such as dicing, picking, mounting and bonding. Besides the fabrication processes of the thin-film Encapsulation, this paper also presents the results of finite element models (FEMs) for the deflection and the mechanical stress of the thin-film caps. Moreover, in order to mount a MEMS chip with the thin- film capsulations and another integrated circuit (IC) chip that controls a MEMS chip in the same package, we have also developed an epoxy reinforcement technique for protecting the thin-film Encapsulations and a topography wafer thinning technique for the MEMS chip. And then the system in package (SiP) for the MEMS and IC chips is fabricated successfully based on the mechanical analysis of the SiP process.
