“…One immuno-sensor used amino capped platinum porous nanoparticles whereas, the other exploited biofunctional carboxyl graphene nanosheets as signal probes for making a highly stable biosensor Wang et al, 2014b). Apart from these, other electrochemical cancer biosensors for protein biomarkers detection are also reported Rezaei et al, 2011;Viswanathan et al, 2012;Yang et al, 2014). Mukundan et al (2009) have developed a fluorescence-based sandwich detection method for the measurement of CEA, a molecule associated with multiple cancer types.…”

“…Somatomedin C is becoming increasingly important in research for a variety of diseases from hearing loss to cancer. Rezaei et al 155 reported their use of gold nanoparticles and monoclonal antibodies on modified gold electrodes for novel detection of insulin-like growth factor-1. Cyclic voltammetry and electrochemical impedance spectroscopy ensured proper function of the immunosensor and preliminary results suggest its effective detection in human serum samples.…”

By using a solid KCl melt in conjunction with an Ag/AgCl component, Vanau et al. 8 were able to fabricate an SSRE designed specifically for beverage industry applications. They found that this SSRE had a wide range of pH use, stable potentials, and small drift potentials (1 mV at room temperature over 3 months time). The reported stability and lifetime of this reference electrode make it particularly applicable for the food industry. In addition to food industry, engine diagnostics are utilizing SSRE to assess efficiency. Oxygen sensors have long been utilizing yttria-stabilized zirconia-based potentiometric components. Recently, Mn-based oxides have been studied to find a suitable SSRE to ensure accurate on-board diagnosis for engines. Miura et al. 9 found Mn 2 O 3 -sensing electrodes to function with excellent sensitivity and has great potential for miniaturization.Rius-Ruiz et al. 10 recently reported a carbon nanotube (CNT)-based SSRE. The most successful design tested utilized a photopolymerized n-butyl acrylate polymer in conjuction with SWCNTs, acting as the transducer layer. This type of transducer layer was often superior to alternative solid transducers, and the resulting SSRE proved insensitive to room lighting. The superior characteristics of this reference electrode as well as its ease of fabrication allow for potential widespread usage in a multitude of systems.Other Papers of Interest. To ensure reference electrodes keep up with current miniaturization trends, it has become challenging to find suitable materials for all potential applications. One such challenging arena is that of steel corrosion monitoring. Muralidharan et al. 11 developed a NiFe 2 O 4 reference electrode due to its superior fabrication cost and ease and its resistance to corrosion. The resulting electrode exhibited stability and low polarization currents in a calcium hydroxide solution, which is commonly used in concrete environments.Shibata et al. 12 examined the stability of an Ag/AgCl reference electrode with the novel salt bridge 1-methyl-3-octylimidazolium bis(trifluoromethanesulfonyl)-amide. This bridge was proposed and found to be superior in order to avoid the interference found using alternate ionic liquid salt bridges, such as KCl, while experimenting in phthalate buffer. Further evaluation of stability is necessary; however, the initial findings suggest this ionic liquid salt bridge is promising. Huang et al. 13 recently developed a working system using a Nafion strip membrane as an ion-conducting bridge, allowing for electrochemical measurements in pure water. By using this bridge, it is possible to avoid potential leaching contaminants and gain higher accuracy.Measuring the electrodeposition of boron melts is a challenge to researchers due to the unknown chemistry of KF-KCl-KBrF 4 . Pal et al. 14 fabricated an Ag/AgCl reference electrode that was found to be reversible and to have suitable stability and nonpolarizability. This will allow for the first available measurements of KF-KCl-KBrF 4 chemistry at high tempera...
