“…Zinc-based nanosensors are placed as a nanowire in nanotube layers and are used to detect glucose. Array and nanowire layers of ruthenium [ 80 ] and gold [ 81 ] are other materials used in nanosensors that have increased the surface and electrochemical enhancement compared to conventional electrodes. Furthermore, to produce nanoscale-modified properties at the structural electrode surface, nanosensors can be upgraded with new nanoparticles, namely, gold [ 49 ], platinum [ 82 ], and palladium [ 83 ] nanoparticles in skins to help electron transmit and surge sensor surface area.…”

Diabetes mellitus (DM) follows a series of metabolic diseases categorized by high blood sugar levels. Owing to the increasing diabetes disease in the world, early diagnosis of this disease is critical. New methods such as nanotechnology have made significant progress in many areas of medical science and physiology. Nanobiosensors are very sensible and can identify single virus particles or even low concentrations of a material that can be inherently harmful. One of the main factors for developing glucose sensors in the body is the diagnosis of hypoglycemia in individuals with insulin-dependent diabetes. Therefore, this study aimed to evaluate the most up-to-date and fastest glucose detection method by nanosensors and, as a result, faster and better treatment in medical sciences. In this review, we try to explore new ways to control blood glucose levels and treat diabetes. We begin with a definition of biosensors and their classification and basis, and then we examine the latest biosensors in glucose detection and new biosensors applications, including the artificial pancreas and updating quantum graphene data.

“…Nanomaterials provide advantages, such as a high surface area, enhanced electron transfer from enzyme to electrode and the ability to include additional catalytic steps. For example, nanowires and nanotube arrays made of zinc oxide [ 8 , 9 , 10 ], ruthenium [ 11 ] and gold [ 12 ] have been used to increase the surface area with electrochemical reaction improvements compared to conventional electrodes. Similarly, nanoparticles of palladium [ 13 ] and gold [ 14 ] have been used in membrane configurations to enhance electron transfer.…”

Blood glucose monitoring is considered the gold standard for diabetes diagnostics and self-monitoring. However, the underlying process is invasive and highly uncomfortable for patients. Furthermore, the process must be completed several times a day to successfully manage the disease, which greatly contributes to the massive need for non-invasive monitoring options. Human serums, such as saliva, sweat, breath, urine and tears, contain traces of glucose and are easily accessible. Therefore, they allow minimal to non-invasive glucose monitoring, making them attractive alternatives to blood measurements. Numerous developments regarding noninvasive glucose detection techniques have taken place over the years, but recently, they have gained recognition as viable alternatives, due to the advent of nanotechnology-based sensors. Such sensors are optimal for testing the amount of glucose in serums other than blood thanks to their enhanced sensitivity and selectivity ranges, in addition to their size and compatibility with electronic circuitry. These nanotechnology approaches are rapidly evolving, and new techniques are constantly emerging. Hence, this manuscript aims to review current and future nanomaterial-based technologies utilizing saliva, sweat, breath and tears as a diagnostic medium for diabetes monitoring.

Worldwide, diabetes is a rapidly growing problem that is managed at the individual level by monitoring and controlling blood glucose levels to minimize the negative effects of the disease. Because of limitations in diagnostic methods, significant research efforts are focused on developing improved methods to measure glucose. Nanotechnology has impacted these efforts by increasing the surface area of sensors, improving the catalytic properties of electrodes and providing nanoscale sensors. Herein, we discuss developments in the past several years on both nanosensors that directly measure glucose as well as nanomaterials that improve glucose sensor function. Finally, we discuss challenges that must be overcome to apply these developments in the clinic. KeywordsBiosensor; Glucose Oxidase; Direct Oxidation; Quantum Dot; Nanoparticle; Nanosensor; Carbon nanotube; Smart tattoo; Continuous monitoring Diabetes and Blood Glucose MonitoringDiabetes is a rapidly growing problem, currently affecting 24 million people in the US alone [1]. This number could increase to 44.1 million by 2034 with treatment costs approaching $336 billion (in 2007 dollars) [2]. Diabetes can lead to complications such as serious as lower-limb amputations, blindness, and cardiovascular disease [1]. Although there is no cure for diabetes, patients can reduce disease-associated complications through the tight control of blood glucose levels [1].In order to attain optimal control, patients must monitor their blood glucose levels. Currently, this requires a patient to obtain a small sample of blood, usually via a finger prick. Blood is placed onto a sensor test strip that is then read by a handheld electronic reader, which reports the blood glucose concentration. These sensors are based on electrochemical enzymatic measurements ( Figure 1) with screen printed electrodes [3] and provide rapid and accurate measurements of blood glucose without the need for laboratory analysis. However, there are limitations to this approach including painful sampling, analyses cannot be performed if the patient is otherwise occupied (e.g. sleeping) and large fluctuations between sampling time points are missed [4,5].

For many diabetics this provides satisfactory data for the control of blood glucose levels. However, inherent in this approach lays ...
