Metal nanoparticles, in general, and gold nanoparticles, in particular, are very attractive because of their size- and shape-dependent properties. Biosynthesis of anisotropic gold nanoparticles using aqueous extract of Madhuca longifolia and their potential as IR blockers has been demonstrated. The tyrosine residue was identified as the active functional group for gold ion reduction. These gold nanoparticles were characterized by of UV-Vis spectrophotometer, FTIR, TEM and HrTEM. The presence of proteins was identified by FTIR, SDS-PAGE, UV-Vis and fluorescence spectroscopy. The micrograph revealed the formation of anisotropic gold nanoaprticles. The biologically synthesized gold nanotriangles can be easily coated in the glass windows which are highly efficient in absorbing IR radiations.
金属纳米粒子，一般来说，和金纳米粒子，特别是，由于其尺寸和形状依赖性的特性而非常有吸引力。已经证明，使用 Madhuca longifolia 的水提物生物合成各向异性金纳米粒子及其作为 IR 阻滞剂的潜力。酪氨酸残基被确定为还原金离子的活性功能基团。这些金纳米粒子通过紫外可见分光光度计、傅里叶变换红外光谱仪、TEM 和 HrTEM 进行了表征。通过傅里叶变换红外光谱仪、SDS-PAGE、紫外可见光谱和荧光光谱鉴定了蛋白质的存在。显微镜照片显示出各向异性金纳米粒子的形成。生物合成的金纳米三角体可以很容易地涂覆在玻璃窗上，这些玻璃窗在吸收 IR 辐射方面非常有效。
