Biocompatible interfaces for biosensors

Sintesis Selulosa Asetat dari Limbah Pengolahan Agar

“…Selulosa dapat dimanfaatkan di bidang industri dalam bentuk murninya maupun produk turunannya (derivat selulosa). Salah satu produk turunan selulosa yang banyak dibutuhkan oleh industri adalah selulosa asetat, yaitu serat untuk tekstil, filter rokok, plastik, film fotografi, pelapis kertas, membran, dan kemasan (Edgar et al, 2001;Choi et al, 2002;Morti et al, 2003;Cetin et al,2004;Gill et al, 2005;Kosaka et al, 2005;Idris & Yet, 2006;Wibowo et al, 2006;Guilminot et al, 2007;Fischer et al, 2008;Gemili et al, 2010;Robertson et al, 2012).…”

Preparation, characterization and applications of ultrathin cellulose acetate Langmuir–Blodgett films

“…2 Their inherent mechanical and chemical stability together with structural fine tuning, which is made possible through controlled solvent casting, has allowed for versatile separation capabilities. 3,4 A particular application where precise transport selectivity is of special importance is in the field of biosensors, where CA barrier membranes have been used in combination with immobilized biomolecules such as enzymes [5][6][7][8][9] as well as bacterial systems. 10 The majority of these CA based membranes constitute thick film structures (of the order of microns) where information is unavailable to discriminate membrane surface versus bulk selectivity properties.…”

Mode and polarization state selected guided wave spectroscopy of orientational anisotrophy in model membrane cellulosic polymer films: relevance to lab-on-a-chip

“…The relative degree of acetate substitution at C (2) , C (3) , and C (6) depends upon the method used to prepare the CA. The distribution of these from one repeat unit to the next is not known.…”

“…For example, if the waveguide streak is not exactly parallel to the vertical entrance slit of the monochromator, this situation would correspond to a rotation of the waveguide coordinate system about the Z-axis. (2) where is the angle between X and X. The Raman tensor elements expected to participate in each polarized measurement (longitudinal field components) are summarized in Table 4 assuming misalignment about all three axes.…”

“…1 For filtering, cellulosics offer biocompatibility and a range of permeabilities for biosensors [2][3][4][5] . Lammertink et al 6 have reviewed the use of membranes in microfluidic devices integrated for functionality on a chip.…”
