“…This causes substantial problems in electrochemical detection of dopamine. Despite several sophisticated detection systems, the sensitivity of electrochemical detection is typically above 20 nm of DA (see [34] and references herein). Supported BLM can be advantageously used for detection DA and other hormones, like epinephrine (EP, known as adrenaline).…”

Lipid membrane based nano-biosensors have been exploited in biosensor technology for the last 30 years. Recent advances in the stabilization of lipid membranes have recently increased the number of publications; however, the applications for the construction of medical devices for diagnostics are still limited. The objective of the present article is to describe recent methods for the construction of stabilized lipid film biosensors and advances in uses of lipid film based nano-biosensors for medical diagnostics. These novel devices could be used for the quantification of high-risk toxicants in the human body. Such developments include the production of biochips to detect neurotransmitters, proteins, DNA, and small molecules, such as glucose. Recent research is focused on the construction of a portable device that will be commercialized and readily be used by nonskilled personnel for the remote sensing of biomedical interest analytes.

“…This causes substantial problems in electrochemical detection of dopamine. Despite several sophisticated detection systems, the sensitivity of electrochemical detection is typically above 20 nM of DA (see [9,10] and references herein). Due to similarity in oxidation potential there are also difficulties in discrimination between various catecholamines, for example dopamine and epinephrine.…”

“…Our group recently reported two sensitive and selective voltammetric methods for the determination of dopamine in the presence of high concentrations of ascorbic acid by using titanium phosphated silica gel [45] and zirconium phosphated [46] silica gel modified carbon paste electrodes. These modified electrodes showed good analytical figures of merit for selective determination of DA.…”

“…A serious drawback of the electrodes modified by these methods is that the electrode surfaces cannot be renewed in the event of leakage, contamination or passivation. In some of these electrodes, expensive modifiers such as carbon nanotubes [31,[33][34][35][36] mesoporous and ordered mesoporous carbon [37], nanoparticles [38][39][40], or synthetic modifiers that require complicated and time consuming preparation methods [41][42][43][44][45][46] were used for electrode modification.…”
