Abstract

This study investigated the biofouling potential of surface-enhanced Raman scattering (SERS)-based sensor materials in the context of marine environments. Uncoated and monolithic commercial gold (Au) silicon nanopillar array SERS substrates, Au-coated carbon black nanoparticle (AuCB NP) substrates, uncoated and Au sputter-coated in-house SERS, and uncoated and Au sputter-coated glass controls were tested for biofouling potential using Ulva spp. as model biofouling organisms. The mean percentages of Ulva spp. zoospores that adhered per mm² (×10³) on the uncoated and coated Au silicon nanopillar array, AuCB NP, uncoated and Au sputter-coated in-house, and uncoated and Au sputter-coated glass substrates were 10.28%, 5.45%, 10.49%, 3.25%, 24.84%, 12.86% and 7.78%, respectively. Results indicated that surface properties such as hydrophobicity, roughness, Au sputter-coating and the presence of micro-refuges on nano- and microstructured substrates were critical to the biofouling formation.

Ulva spp.基于表面增强拉曼散射的海水质量传感器的生物污垢潜力。

本研究研究了基于表面增强拉曼散射（SERS）的传感器材料在海洋环境中的生物污垢潜力。使用Ulva spp.作为模型生物污垢生物，测试了未涂覆和单片商业金（Au）硅纳米柱阵列SERS基底、涂覆Au的炭黑纳米颗粒（AuCB NP）基底、未涂覆和Au溅射涂覆的内部SERS以及未涂覆和金溅射涂覆的玻璃对照的生物污垢潜力。在未涂覆和涂覆的Au硅纳米柱阵列、AuCB NP、内部未涂覆和Au溅射涂覆以及未涂覆和金溅射涂覆的玻璃基板上，每mm2（×103）附着的Ulva spp.游动孢子的平均百分比分别为10.28%、5.45%、10.49%、3.25%、24.84%、12.86%和7.78%。结果表明，表面性质，如疏水性、粗糙度、Au溅射涂层以及纳米和微结构基底上存在的微避难所，对生物污垢的形成至关重要。

期刊介绍： Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion. Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context. Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
