Dear Editor, Liver transplantation(LT) is the only curative therapy for patients with endstage liver disease(He et al., 2023; Ling et al., 2022). Post-transplant hypertriglyceridemia(PTHT), which has an incidence of up to 32.8% in 6 months after LT, is one of the major post-transplant complications(Toshima et al., 2020).

金属氧化物纳米晶体具有独特的尺寸及形貌依赖的光学/光电特性,因此实现金属氧化物纳米晶的可控合成对其光电应用具有重要意义.然而,目前对于金属氧化物纳米晶尺寸和形貌的关键影响因素研究相对较少.在本工作中,我们发现,在前驱体反应过程形成的副产物—醋酸,通过影响纳米晶的成核过程,对氧化铟纳米晶的形貌控制起了决定性作用.具体地,醋酸过量时会诱导纳米晶各向异性生长,生成纳米花;而在少量或者无醋酸条件下,所得氧化铟纳米晶呈球形.进一步地,我们探究了氧化铟纳米晶的几何形状对表面等离基元性质的影响.通过调节几何形状,可以得到在近红外到中波红外具有可调谐的表面等离基元共振吸收的等离子体纳米晶,同时展现出优异的稳定性.本工作深入探究了金属氧化物纳米晶的几何形状影响机制,为基于等离子体金属氧化物纳米晶的光电和光热应用提供更多指导.
