利用表面等离子体共振金纳米粒子可以增强光学相干层析成像(OCT)图像的对比度。为了改善金纳米颗粒在体内通过生物屏障的不良转运,需要一种有效的递送策略。在这项研究中,通过微针和超声分别改善了金纳米颗粒的渗透和分布,并证明了这种抗体偶联聚乙二醇化金纳米颗粒的多模式递送增强了仓鼠口腔发育不良模型的体内OCT图像的对比度。
Contrast in optical coherence tomography (OCT) images can be enhanced by utilizing surface plasmon resonant gold nanoparticles. To improve the poor in vivo transport of gold nanoparticles through biological barriers, an efficient delivery strategy is needed. In this study, the improved penetration and distribution of gold nanoparticles were achieved by microneedle and ultrasound, respectively, and it was demonstrated that this multimodal delivery of antibodyconjugated PEGylated gold nanoparticles enhanced the contrast in in vivo OCT images of oral dysplasia in a hamster model.
