“…[12][13][14][15] In this regard, a lot of attention has been paid to synthesis of nanostructured materials using natural species such as algae, yeasts, bacteria, fungi, biological compounds, and plant extracts. 16 In such synthesis of metal nanostructures, these compounds act simultaneously as reducing, shape-directing, structure-stabilizing, capping, and aggregation-inhibiting agents due to the proteins, enzymes, carbohydrates, aldehydes, etc.…”

Silver nanoparticles have been synthesized using only Myrtus communis L. leaf extract by a facile procedure without other reagents. The extract played the roles of both reducing and capping agent. The nanoparticles were characterized using field-emission scanning microscopy, and remained stable for at least 3 weeks. Antibacterial activity of the nanoparticles was evaluated toward Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Enterococcus faecalis based on inhibition zone disk diffusion assays. The minimum inhibitory and bactericidal concentrations of the nanoparticles were obtained. Mechanisms for the antibacterial activity were proposed.

A new non‐enzymatic glucose sensor based gold nanoparticle (AuNp)‐chitosan (Ch/AuNp) was developed in this study. Gold nanoparticles were synthesized by using the green synthesis method, in which chitosan is used as both reducing and stabilizing agent. Gold nanoparticle surfaces were modified with different molecular agents (4‐mercaptophenyl boronic acid,MPB, and 1‐decanethiol,DT) being sensitive to glucose. Modified gold nanoparticles were immobilized to electrode surfaces and used for the glucose measurements by the potentiometric method. The best working conditions were determined for the glucose measurements. It was found that linear working range is 0.5–30 mM, while limit of detection is 0.3 mM for the glucose measurement of the prepared non‐enzymatic sensor. It was stated that the prepared sensor could be used at least 6 times and glucose response decreased approximately 10.97 % when it is waited for 30 days. Interference effect of some molecules for glucose measurement was investigated and usability of developed sensor was tested in human blood serum.

“…The blood glucose level in normal person ranges between 70 and 80 mg dL -1 (Gao et al 2015;Heli and Amirizadeh 2016). The increase in the amount of glucose in blood results in type 1 and type 2 diabetes (Kim et al 2015;Hsu et al 2016;Li et al 2016).…”

“…The concentration of glucose in blood serum of patients with type I and type II diabetes can be calculated from the current density of enzymatically released H 2 O 2 (Xia et al 2014;Kim et al 2015;Zhang et al 2016). Compared to electrochemical glucose oxidase enzyme-based biosensors, non-enzymatic glucose biosensors based on metal oxide nanoparticles offer good stability against denaturation, easy to fabricate and facilitate effective glucose oxidase enzyme like catalysis over a wide temperature and pH ranges (Eguílaz et al 2015;Heli and Amirizadeh 2016;Li et al 2016). For these reasons, electrode materials showing enhanced catalytic activity are very important to attain extremely sensitive detection of glucose.…”

Consumption of fruits leads to increase in glucose level in blood for diabetic patients, which in turn leads to peripheral, vascular, ocular complications and cardiac diseases. In this context, a non-enzymatic hybrid glucose biosensor was fabricated for the first time to detect glucose by immobilizing titanium oxide-manganese oxide (TiO 2 -Mn 3 O 4 ) nanocomposite and chitosan membrane on to the surface of Pt working electrode (Pt/TiO 2 -Mn 3 O 4 /chitosan). TiO 2 -Mn 3 O 4 nanocomposite catalyzed the oxidation of glucose to gluconolactone in the absence of glucose oxidase enzyme with high electron transfer rate, good biocompatibility and large surface coverage. Electrochemical measurements revealed the excellent sensing response of the developed biosensor towards glucose with a high sensitivity of 7.073 lA mM -1 , linearity of 0.01-0.1 mM, low detection limit of 0.01 lM, reproducibility of 1.5% and stability of 98.8%. The electrochemical parameters estimated from the anodic process were subjected to linear regression models for the detection of unknown concentration of glucose in different fruit samples.
