Nanotechnology is evolving as a significant discipline of research with various applications. It includes the materials and their applications having one dimension in the range of 1–100 nm. Many chemical and physical protocol have been utilized for the nanoparticles (NPs) fabrication. These protocols are costly, hazardous and consumes high energy. Thus, researchers are inclined towards biological synthesis of NPs using plant and or herbal extract as these methods are simple, sustainable, ecofriendly and cost-effective. Flower is an important part of plants, and contained several phytochemicals such as flavonoids, terpenoids, coumarins, sterol and xanthones which acts as an important precursor for NPs synthesis. These compounds acted as reducing as well as stablishing agent during fabrication processes. They have been thoroughly characterized by various techniques. The fabricated NPs have shown potential antimicrobial activity against bacterial and fungal infections. They have been also used as potential therapeutic agent for human breast cancer, gastric adenocarcinoma cell, colorectal adenocarcinoma cell and pancreas ductal adenocarcinoma cells. Overall, the aim of this review article to facilitates the recent understanding of flower-mediated NPs fabrication (a sustainable and ecofriendly resource), their application in different disciplines and challenges.

纳米技术正在发展成为具有各种应用程序的重要研究学科。它包括一维在1–100 nm范围内的材料及其应用。许多化学和物理方案已经用于纳米颗粒（NP）的制造。这些协议昂贵，危险并且消耗大量能量。因此，研究人员倾向于使用植物或草药提取物进行NP的生物合成，因为这些方法简单，可持续，生态友好且具有成本效益。花是植物的重要组成部分，并包含多种植物化学物质，如黄酮类，萜类，香豆素，甾醇和氧杂蒽酮，它们是NP合成的重要前体。这些化合物在制造过程中充当还原剂和稳定剂。它们已经通过各种技术得到了彻底的表征。制成的纳米粒已显示出对细菌和真菌感染的潜在抗菌活性。它们还被用作人类乳腺癌，胃腺癌细胞，结直肠腺癌细胞和胰腺导管腺癌细胞的潜在治疗剂。总体而言，这篇综述文章的目的是促进人们对花介导的NPs的制造（一种可持续的，生态友好的资源）及其在不同学科和挑战中的应用的最新了解。大肠腺癌细胞和胰腺导管腺癌细胞。总体而言，这篇综述文章的目的是促进人们对花介导的NPs的制造（一种可持续的，生态友好的资源）及其在不同学科和挑战中的应用的最新了解。大肠腺癌细胞和胰腺导管腺癌细胞。总体而言，这篇综述文章的目的是促进人们对花介导的NPs的制造（一种可持续的，生态友好的资源）及其在不同学科和挑战中的应用的最新了解。
