The use of magnetic nanoparticles (MNPs) in sample preparation has gained much attention. Easyto-handle property of MNPs has provided a great promising solution for lab automation. Laboratory robotics and workstations based on magnetic separation are in rapid development process, and increasing efforts are debited for their practical applications in clinical methods. To increase the processing throughput and reduce the risk of cross contamination, we developed a multifunctional module to optimize the workflow of magnetic nucleic acid separation in automated workstation. Three functions (magnetic separation, heating, and shaking) were elaborately combined into this device, by which the 96-well plate-based sample preparation can be completed on site without transferring the plate to other auxiliary modules. Test experiments were carried out on this platform. It was shown that this multifunctional device could cooperate well with our pipetting system, and this new platform exhibited its ability to meet the demands for high-throughput sample preparation.

“…In the synthesis of Au/Ag NRs, the use of soft template received more attention because it does not require subsequent removal of the template. It is worth mentioning that during the whole process of preparing NRs, the parameters including the pH of the solution, the type and amount of the surfactant and coating agent have a significant influence on the radial ratio of NRs, which need to be very tightly controlled [56]. Cetyltrimethylammonium bromide (CTAB) is the most commonly used surfactant and can form rod-shaped micelles in solution, which can effectively control the directional At present, many synthetic methods have been reported to prepare NRs with good dispersibility and uniform particles.…”

Nanomaterials with unique physical and chemical properties have attracted extensive attention of scientific research and will play an increasingly important role in the future development of science and technology. With the gradual deepening of research, noble metal nanomaterials have been applied in the fields of new energy materials, photoelectric information storage, and nano-enhanced catalysis due to their unique optical, electrical and catalytic properties. Nanostructured materials formed by noble metal elements (Au, Ag, etc.) exhibit remarkable photoelectric properties, good stability and low biotoxicity, which received extensive attention in chemical and biological sensing field and achieved significant research progress. In this paper, the research on the synthesis, modification and sensing application of the existing noble metal nanomaterials is reviewed in detail, which provides a theoretical guidance for further research on the functional properties of such nanostructured materials and their applications of other nanofields.

“…Plasmonic gold nanorods (AuNRs) have shown potential for use in a range of cancer diagnostics and therapeutics, such as photoacoustic imaging (PAI) and plasmonic photothermal therapy (PPTT) due to their unique optical properties [1], [2], tuneable surface plasmon resonances (SPRs) [3], relative biocompatibility [4], and functionalisation prospects [5]. The capability to synthesise them in large quantities with highly reproducible and consistent properties is an essential trait for successful clinical translation [6].…”

Plasmonic gold nanoparticles show potential for use in a range of cancer diagnostics and therapeutics, such as photoacoustic imaging (PAI) and plasmonic photothermal therapy (PPTT). Generally in PPTT, continuous wave (CW) lasers are used to destroy cancerous tissue. However, in order to add a diagnostic component through PAI, a pulsed wave (PW) laser is needed. If PPTT can be achieved using PW lasers then combined theranostic applications with the same laser system is possible. Additionally, AuNRs can be many different sizes but exhibit equivalent surface plasmon resonances, so the size may be significant in the efficacy of these modalities. We have demonstrated the potential for gold nanorods to be used for both PAI and PPTT. The Au10s displayed the highest photoacoustic signal amplitude and PPTT efficacy. A PW laser was shown to induce significant cell death to a lung cancer cell line with a fluence below the maximum permissible exposure, indicating the possibility for cancer theranostics with a PW laser.
