中文摘要 | 嚴重發燒伴隨血小板減少症候群(SFTS)是一種新發現的人畜共通傳染病,由SFTS病毒(SFTSV)引起。為了預防和快速診斷病毒,有必要開發快速、高靈敏度的病毒檢測方法。本研究提出了一種無抗體表面增強拉曼散射 (SERS) 方法,使用新型 SERS 晶片,將銀奈米粒子 (AgNPs) 均勻沉積在微碗陣列聚二甲基矽氧烷 (PDMS) 基底上,以有效檢測 SFTSV。微碗陣列PDMS基底是採用鎳模電鑄透過光刻技術直接寫入光阻模板的微米碗陣列結構來製作的。採用自組裝單分子層 (SAM) 方法將 SFTSV 抗原 Gn-mFc 固定在 PDMS 基底上。實驗結果顯示,Gn-mFc在87.3~8728.5 ng/mL的線性檢測範圍內可檢測到,檢測極限(LOD)為51.3 ng/mL。所提出的SERS感測方案具有直接檢測(無需抗體和表面嫁接處理)、樣品用量小(20 μ L)、偵測速度快(<5分鐘),無需專業操作人員。 |
英文摘要 | Severe fever with thrombocytopenia syndrome (SFTS) is a newly identified zoonotic infectious disease caused by the SFTS virus (SFTSV). For virus prevention and rapid diagnosis, the development of fast and highly sensitive virus detection methods is necessary. In this study, an antibody-free surface-enhanced Raman scattering (SERS) method using novel SERS chips with silver nanoparticles (AgNPs) uniformly deposited on a microbowl array polydimethylsiloxane (PDMS) substrate was proposed for efficient detection of SFTSV. The microbowl array PDMS substrate was fabricated using a nickel mold electroformed through a photolithographically directly written micron bowl array structure of a photoresist template. The SFTSV antigen Gn-mFc was immobilized to the PDMS substrate using the self-assembly monolayer (SAM) method. The experimental results showed that Gn-mFc can be detected in a linear detection range from 87.3 to 8728.5 ng/mL with a limit of detection (LOD) of 51.3 ng/mL. The proposed SERS sensing scheme has the advantages of direct detection (no antibodies and no surface grafting treatment required), small sample usage ( 20 μ L), fast detection (<5 min), and no need for professional operators. |
