A novel, simple, and highly sensitive method was developed to detect the concentration of tyrosine-derived azo dye indirectly using silver nanocubes (AgNCs) as a substrate on a super-hydrophobic silver film by surface-enhanced Raman spectroscopy (SERS). Diazotization-coupling reaction occurred between diazonium ions and the phenolic tyrosine, resulting in three new typical peaks in the SERS spectrum of the azo dye that was formed on the AgNCs, indicating strong SERS activity. Subsequently, the limit of detection of this approach was as low as 10−12 M for tyrosine. Moreover, the SERS intensities of the three typical SERS signals of the analyte were linearly correlated with the logarithm of concentration of the Tyrosine. The proposed method shows great potential for tyrosine detection in the urine samples of normal humans.

“…After preparing a polymer solution with NPs, a nanocomposite film is easily obtained by spin-coating or casting methods. In addition to the above three processes, it is also possible to synthesize a polymer-metal nanocomposite film after making a polymer film, which contains a precursor of NPs, and then induce chemical 12 , 13 , photoinduced 14 – 18 , microwave 19 , or thermal reduction 20 – 23 to produce NPs in the polymer matrix. These methods are called in situ reduction methods.…”

We demonstrate the rapid in situ synthesis of polymer-metal nanocomposite films using a CO2 laser at 10.6 μm. The mechanism of our method is that the precursor of the metal nanoparticles, i.e., the metallic ions, is very rapidly reduced in the laser-heated polymer matrix without any reducing agent. Unlike other known laser-induced reduction methods using UV lasers, which produce radicals to promote reduction, the CO2 laser energy is mainly absorbed by the glass substrate, and the laser-heated substrate heats the polymer matrix through heat diffusion to promote reduction. The superiority of the use of CO2 lasers over nanosecond visible~UV lasers is also demonstrated in terms of the damage to the film. The developed method can be a new alternative to quickly synthesize a variety of polymer-metal nanocomposite films.

“…So far, many fabrication strategies to prepare silver NPs have been built, including photoreduction [27], microemulsion [28], biochemistry [29], solvothermal reaction [16], template strategy [30], electrochemical deposition [31], bionic technology [32], seeding growth approach [33], and micro-wave [34] [35] assisted reduction. Among all these synthesis methods, due to the ability to accurately design and engineer structures on nanometer scale, hydrothermal method have been proved to be a fascinating choice for selecting geometric variables (e.g., size and shape) and tailoring the optical properties of silver NPs to boost the SERS signals in a predictable way [36].…”
