“…It is important to highlight that the method herein reported can be used for determination of ethanol in other samples as alcoholic beverages [33][34][35]. Furthermore, the working electrode can be easily changed in order to monitor other volatile compounds like sulfite as sulfur dioxide [51], total ammonia and carbon dioxide [52].…”

Biosensors are the switching channels that make sense. The biosensors have found an empirical role in health applications (e.g. clinical diagnostics) as they represent the technological counterpart of living senses. On a global scale, alcohol analysis is indispensable for criminal justice systems, monitoring medical conditions of HIV patients & pregnant women as well as public safety issues regarding pilots, metro drivers, doctors etc. For addressing the clinical and toxicological problems, much advancement in the improvement of biosensors have been witnessed in recent decades. Currently, electrochemical biosensors dominate the field which harnesses the synergistic action of enzymes and nanomaterials for the analysis of ethanol. The enzymatic biosensors are the most explored biosensing devices among all the types of biosensors, and employment of nanomaterials has paved a way to the further improvements in this gem of a discovery. The relative comparison to precise the alcohol biosensors has been aptly discussed in the review on the basis of several analytical properties including fabrication, linearity, sensitivity, response time, detection limit as well as storage stability. Finally, the recent trends and emerging future prospects of alcohol biosensors have been reviewed.

ÖZ Bu çalışmada, yenilebilir bir mantar olan Boletus edulis'in doku homojenatı kullanılarak, etanol tayini için doku temelli amperometrik bir biyosensör geliştirildi. Bu amaçla; mantar doku homojenatı, jelatin ve çapraz bağlayıcı ajan glutaraldehit yardımıyla camsı karbon çalışma elektrotu üzerine immobilize edildi. Biyosensör cevabı üzerine pH ve sıcaklığın etkisi araştırıldı. İmmobilizasyon koşullarının optimizasyonu için; doku homojenatı miktarı, jelatin miktarı ve glutaraldehit konsantrasyonu belirlendi. Optimum koşullarda hazırlanan B. edulis doku temelli biyosensörün etanol için doğrusal tayin aralığı, 5.0-150 mM ve tayin sınırı, 2.5 mM olarak bulundu. Ayrıca, biyosensörün tekrarlanabilirlik çalışmaları sonucunda, varyasyon katsayısı (V.K.) ve standart sapma (S.S.) değerleri sırasıyla % 0.7212 ve ±0.7209 (n=10) olarak hesaplandı. Biyosensörün depo kararlılığı incelendi ve +4 °C'deki depolamanın 20. gününde aktivitesinin % 76.3'ünün koruduğu gözlendi. Hazırlanan biyosensör, etanol derişimi bilinen örneklerin analizi için kullanıldı. ABSTRACTIn this study, an amperometric biosensor based on tissue for ethanol determination was constructed using tissue homogenate of Boletus edulis which is an edible mushroom. For this purpose, tissue homogenate of mushroom was immobilized onto the glassy carbon electrode using gelatin and glutaraldehyde which is cross-linking agent. Effects of pH and temperature on biosensor response were investigated. The amounts of tissue homogenate, amounts of gelatin and glutaraldehyde concentration were determined for optimization of immobilization conditions. The linear range for ethanol was 5.0-150 mM and the detection limit was 2.5 mM, of biosensor based on B. edulis tissue prepared under optimal conditions. Also, in repeatability studies, variation coefficient (C.V.) and standard deviation (S.D.) were calculated as 0.7212 % and ±0.7209, respectively. The biosensor retained 76.3% of its original activity after 20 days of storage at +4 °C. The prepared biosensor was used for analysis of ethanol samples with known concentrations.
