In a recent paper [Physica E 114(2019) 113562] Jafarzadeh et al. have studied the optical and dielectric properties of Ag nanoparticles decorated by herceptin. The reflectance spectra of the specimens have been calculated using an incorrect approach and obtained results are unreasonable. Also, the erroneous values of reflectance have been used to study the optical properties of the samples. Consequently, reported optical parameters that have been calculated based on reflectance such as refractive index, extinction coefficient, as well as real and imaginary parts of the optical dielectric constant are incorrect.

评论：“用赫赛汀装饰的Ag纳米颗粒的结构，光学和介电研究” [Physics E 114（2019）113562]

在最近的论文[Physica E 114（2019）113562]中，Jafarzadeh等人。已经研究了赫赛汀修饰的银纳米颗粒的光学和介电性能。使用不正确的方法计算了样品的反射光谱，并且获得的结果不合理。而且，反射率的错误值已被用于研究样品的光学性质。因此，已根据反射率（例如折射率，消光系数以及光学介电常数的实部和虚部）计算出的报告光学参数不正确。
