“…The physical explanation of these effects was reported by Otto and Kretschmann [40]. The SPR configuration proposed by Daniyal et al [39] is the most-used (see Figure 7) one, and it is based on the "angular interrogation" approach, since the wavelength of the incident light is kept constant, and the angle of incidence of the light is varied. In fact, in this configuration, a monochromatic and p-polarized light is used for exciting a surface plasmon that propagates along a metal surface.…”

“…Surface plasmon resonance (SPR) optical sensors offer large advantages in terms of detection limit, sensitivity, and selectivity when compared with other sensing schemes, and for this reason, many researchers have focused their attention on these sensing devices, starting in the 1990s [39]. The SPR effect was observed by Wood in 1902, when he sent a monochromatic polarized light beam on a diffraction grating and he noticed a pattern of white and dark bands.…”

Phenolic compounds are particularly dangerous due to their ability to remain in the environment for a long period of time and their toxic effects. They enter in the environment in different ways, such as waste from paper manufacturing, agriculture (pesticides, insecticides, herbicides), pharmaceuticals, the petrochemical industry, and coal processing. Conventional methods for phenolic compounds detection present some disadvantages, such as cumbersome sample preparation, complex and time-consuming procedures, and need of expensive equipment. Therefore, there is a very large interest in developing sensors and new sensing schemes for fast and easy-to-use methods for detecting and monitoring the phenolic compound concentration in the environment, with special attention to water. Good analytical properties, reliability, and adaptability are required for the developed sensors. The present paper aims at revising the most generally used optical methods for designing and fabricating biosensors and sensors for phenolic compounds. Some selected examples of the most interesting applications of these techniques are also proposed.

“…At two dielectric media interfaces, any metal holding a large number of free electrons such as gold, silver, copper and aluminum is positioned [ 56 , 57 , 58 ]. However, gold is the most stable and sensitive metal compared to others, so it is very suitable to be used as a metal film [ 59 , 60 , 61 , 62 , 63 , 64 , 65 ]. SPR will occur under complete conditions of internal reflection when plane-polarized light hits the gold-coated film prism [ 66 , 67 , 68 ].…”

Insecticides are enormously important to industry requirements and market demands in agriculture. Despite their usefulness, these insecticides can pose a dangerous risk to the safety of food, environment and all living things through various mechanisms of action. Concern about the environmental impact of repeated use of insecticides has prompted many researchers to develop rapid, economical, uncomplicated and user-friendly analytical method for the detection of insecticides. In this regards, optical sensors are considered as favorable methods for insecticides analysis because of their special features including rapid detection time, low cost, easy to use and high selectivity and sensitivity. In this review, current progresses of incorporation between recognition elements and optical sensors for insecticide detection are discussed and evaluated well, by categorizing it based on insecticide chemical classes, including the range of detection and limit of detection. Additionally, this review aims to provide powerful insights to researchers for the future development of optical sensors in the detection of insecticides.

S on yıllarda, canlılar ve halk sağlığı için önemli bir tehdit oluşturan fenol ve bileşiklerinin tespit edilmesi önem kazanmaktadır. Bu çalışmada, fenolün tespiti için moleküler baskılama yöntemi temel alınarak fenol baskılanmış yüzey plazmon rezonans (SPR) sensörler tasarlanmıştır. Fenol moleküllerine ait boşluklara sahip polimerik film hazırlanarak UV polimerizasyonu ile SPR sensör yüzeyinde oluşturulmuştur. 0.15 ile 10 nM arasındaki tayin aralığında en düşük saptama sınırı 0.022 nM'dir. Ayrıca, seçicilik katekolün yarışmacı ajan olarak seçilmiş ve seçicilik deneylerini gerçekleştirilmiştir. Genel olarak, moleküler baskılama yaklaşımı ile hazırlanan fenol baskılanmış SPR sensörünün fenol için oldukça hassas ve seçici olduğu bulunmuştur. Fenol baskılı SPR sensörleri, yüksek seçicilikleri, tekrar kullanılabilirliliği ve hızlı yanıtları özelliği ile mevcut fenol belirleme yöntemlerine alternatif yeni bir yöntem olarak kullanılmak düşünülmektedir.
