In the present work, we report the physico-chemical properties and structural characteristics of special polyhydroxy fatty acid nanoparticles after their fusion by means of attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electronic microscopy (SEM), atomic force microscopy (AFM), and light microscopy. All the characteristics and properties investigated have an important degree of similarity to the native plant cutin, the main biopolymer present in the plant cuticles. The supramolecular organization of these polymerized prime nanoparticles after their interaction on cellulose substrate and isolated cuticle samples, simulating the in vivo conditions in epidermal plant cells, strongly suggests a growth of these nanoparticles after a self-assembly process.
在本工作中，我们通过衰减全反射-傅里叶变换红外光谱（ATR-FTIR）、X 射线衍射（XRD）、差示扫描量热法（DSC）、扫描电子显微镜（SEM）、原子力显微镜（AFM）和光学显微镜，报道了特殊多羟基脂肪酸纳米粒子融合后的物理化学性质和结构特征。所有研究的特性和性质与天然植物角质的主要生物聚合物具有重要的相似程度。这些聚合原纳米粒子在与纤维素底物和分离的角质样本相互作用后的超分子组织，模拟了表皮植物细胞中的体内条件，强烈表明这些纳米粒子在自组装过程后会生长。
