“…However, the reason for the coloring has been scientifically elucidated not too long ago. The deep-red color of gold colloids with a very large extinction coefficient is due to the plasmonic oscillation of the free electrons confined in the nanoparticles and coupled with the green light with a wavelength of approximately 520 nm, resulting in the formation of the LSP [64,65]. In other words, green light with a wavelength of 520 nm can be confined to nano-sized (approximately 5-20 nm) gold colloids.…”

Pathogens of Emerging Infectious Diseases (EIDs) have sometimes caused serious public health threats. Researchers have put in significant efforts to not only explore and improve the existing therapeutic methods but also prevent the spread of the pathogen. The present COVID-19 pandemic requires administrators and healthcare professionals to make unprecedentedly difficult and rapid countermeasures. The most difficult challenge is that asymptomatic people with infection can sometimes cause clusters of infections. Identification and tracking have always been delayed since diagnostic confirmation relies solely on real-time reverse transcription polymerase chain reaction (RT-PCR) analysis, which requires a long time for the analysis and sometimes gives false positive or negative results, creating further confusion to administrators and healthcare professionals and increasing the risk of infection. This fact indicates that one of the most important keys of infection control when encountering a new EID, including the latest COVID-19, is the extensive use of an effective diagnostic device that can rapidly characterize the pathogen and provide quantitative information. It should be noted that serious respiratory infections, such as COVID-19 and SARS, and also some foodborne, zoonotic, animal, and plant infectious diseases, are a serious threat to the general public. In particular, mutations in zoonotic pathogens that cause human diseases such as H5N1 and H1N1 would be a greater threat to the human society both now and in the future. Countermeasures against these infectious diseases will strongly rely on rapid and precise diagnosis, and the development of diagnostic devices is very crucial. This review describes the requirements and the issues pertaining to diagnostic devices, strategies to achieve ultra-high sensistivity, and the principles of the recently developed analytic methods, for the benefit of frontline users, including healthcare professionals and the representatives of the diagnostic equipment at the institutions.

“…The metal silver deposited on TiNT layer with photo-assisted deposition (PAD) method. Moreover, TiNT has shown to be able to increase osteoblast cell adhesion and influence cellular behavior to enhance tissue engineering [12]. It is generally accepted that modification titanium alloys for improved antibacterial properties and osseointegration is required.…”

The development of Ti 6 Al 4 V based anti bacterial dental implant modified with TiO 2 nanotube arrays doped silver metal (Ag) AIP Conference Proceedings 1840, 080006 (2017) Abstract.The present paper is focused on comparative behavior of nanotubes growth on Ti-6Al-4V and Ti-6Al-7Nb alloy using electrochemical anodization method. These alloys were anodized in electrolytes solution containing glycerol, water and 0.5wt.% of NH4F. Silver-doped TiO2 nanotubes were synthesized using photo-assisted deposition (PAD) at various Ag loading concentration in 0.05 M, 0.10 M, and 0.15 M. The phase composition and morphological characteristics were investigated by XRD and FESEM/EDX, respectively. The surface wettability was measured by contact angle meter. The results showed that TiO2 nanotubes can be grown on these surface alloys. XRD profiles revealed crystal formation of anatase, rutile and Ag on these surface alloys. According to FESEM images, the average nanotube diameter of Ti-6Al-4V alloy and Ti-6Al-7Nb alloy are 134 nm and 120 nm, respectively. EDX-Mapping analysis showed that Ag desposited over surface of TiO2 nanotubes. The surface wettability indicated hydrophilicity properties on Ti-4Al-4V alloy and Ti-6Al-7Nb alloy surface. This study may contribute to the development of silverdoped TiO2 nanotubes on Ti-6Al-4V alloy and Ti-6Al-7Nb alloy can be considered in various photocatalytic applications such as biomedical devicesdue to photocatalytic mechanism and antibacterial ability.
