Considered in this paper are the factors influencing sensitivity of analytical devices based on surface plasmon resonance phenomenon. The decrease in temperature influence on sensitivity of these devices can be reached using thermo stabilization of the whole device with flow cells for studied substances. Adduced here are some results concerning the influence of deposition geometry for nano-dimensional gold layer covering the surface of operating element on sensitivity of these devices.
Анотація. Оптичні клеї широко застосовуються в оптичному виробництві, при цьому оптична якість з'єднання залежить від узгодження показників заломлення клею та матеріалу деталей, а технологічність процесу з'єднання-від оптимальної швидкості полімеризації. Запропоновано метод на основі явища поверхневого плазмонного резонансу для контролю у реальному часі процесу полімеризації оптичних клеїв, що показано на прикладі фотополімерних клеїв марок Akrol-3-360 і UV630. По розрахованим швидкостям та тривалості фотополімеризації визначено, що клей марки UV630 має на 25% більшу швидкість полімеризації та майже у два рази менший термін полімеризації, ніж клей марки Akrol-3-360. Ключові слова: поверхневий плазмовий резонанс, показник заломлення, клей, полімеризація, ультрафіолетове випромінювання. Аннотация.

Optical adhesives are widely used in optical production, with the optical quality of the connection depends on the matching of the refractive indices of the glue and the material of the parts, and the technological process of the connection-from the optimal rate of polymerization. A method based on the phenomenon of surface plasmon resonance for real-time control of the polymerization process of optical adhesives is proposed, as demonstrated by the example of the Akrol-3-360 and UV630 photopolymer adhesives. According to the calculated speed and duration of photopolymerization, the UV630 grade adhesive has a 25% higher polymerization rate and almost twice the polymerization time than the Akrol-3-360 grade adhesive.
The article presents a new developed method, which is able to detect the chicken infectious bronchitis virus (IBV) antigen in real time in various buffer solutions, using the surface plasmon resonance (PPR) nanobiosensor of the Plasmon-6 device. The PPR method is hypersensitive to changes in external factors, including the interaction of antigen (coronavirus) and specific antibodies. If the interaction does not happen, the resonance occurs at other angular parameters of the position of the sensitive PPR element relative to the laser radiation. Therefore, the PPR method is becoming a new effective rapid technique of viral pathogen detection, which is important for effective control over infectious diseases spreading. The possibility of IBK virus detection by the PPR sensor response, with preliminary immobilization of antigen or antibodies, is shown, involving the device "Plasmon- 6". The duration of the experiment is about 2 hours, which significantly saves research time compared to other methods (6-48 hours). The changes in the resonance angle in the range of 360-500 angle. sec when the IBC virus antigen binds to serum antibodies in water (distilled) were detected. The angular shift of the nanosensor resonance was determined when the IBC virus antigen bound to the serum antibodies in the PBS, which averaged 354 angular seconds. The possibilities of using the PPR method for express detection of the coronavirus infections pathogen in animal fluids in real time are demonstrated in article. Taking into account the significant social and economic negative consequences of the Coronaviridae virus family members and considering the current situation with the worldwide spread of COVID-19, the representative of the coronavirus family – the Infectious Bronchitis virus has been selected as a model.
