“…Recently, ITO films have been used as work electrode in the development of bioengineering devices such as ion sensors and biosensors [5][6][7] . The emerging sensor and biosensor technology based on ITO films has emerged as an advantageous alternative for applications in medicine 8,9 . ITO can also be applied to detect H + ions.…”

Polycrystalline ITO films with good optoelectronics characteristics and homogeneous surface has been obtained upon annealing at 550 °C in N 2 atmosphere using a low-cost chemical vapor deposition (CVD) system. The films were evaluated as pH sensors in separative extended gate field-effect transistor (SEGFET) apparatus, exhibiting a sensitivity of 53 mV/pH, close to the expected Nernstian theoretical value for ion sensitive materials. The use of CVD process to synthesize ITO, as described here, may represent an alternative for fabrication of SEGFET pH sensors at low cost to be used in disposable biosensors since H + ions are the product of several oxireductase enzymes.

“…Its transparency facilitates morphological observation of cells, while its conductivity makes it suitable for use as the working electrode in electrochemical experimentation [16]. ITO electrodes are therefore a potential alternative to gold electrodes as they combine conductivity with the ability to accommodate simultaneous optical investigation using phase-contrast and fluorescence microscopy [17].…”

“…Investigation verified that growth of cells on indium tin oxide sensor surface was comparable with growth of cells in tissue culture flasks (Moore et al, 2009). ITO electrodes can therefore be considered a valid alternative to gold electrodes as they can provide both optical and electrical information during the experiment (Choi et al, 2007). The experiments were conducted using different cell lines (e.g.…”
