纳米颗粒（NP），即具有低于100 nm的一个或多个尺寸的颗粒，目前正在工业规模上通过化学和物理方法合成。然而，这些方法的综合NP不适合可持续发展目标。通过化学和物理方法的NP合成需要高温和/或高压，导致高能耗和产生大量废物。近年来，对纳米颗粒合成的研究已经转向更绿色和生物的方法，通常使用微生物。生物方法比化学和物理方法有许多优点。反应在标准温度和压力下在水溶液中催化（成本效益和低能量合成）。这种方法不需要溶剂或有害化学物质，使NP生物合成成为一种更绿色，更环保的方法。此外，通过微生物合成NP不需要使用纯的起始材料;因此，它可以同时用于污染水、土地和废物的生物修复以及NP的生物合成。因此，NP的生物合成有助于实现可持续发展目标，而替代的物理和化学方法仅利用稀缺和昂贵的资源用于NP合成。纳米颗粒目前正在通过化学和物理方法在工业规模上合成。然而，这些合成方法不符合可持续发展目标，因为它们需要高温和/或高压，导致高能耗和产生大量废物。近年来，对纳米颗粒合成的研究已经转向更绿色和生物的方法，通常使用微生物。
Nanoparticles (NPs), particles having one or more dimensions below 100 nm, are currently being synthesized through chemical and physical methods on an industrial scale. However, these methods for the synthesis of NPs do not fit with sustainable development goals. NP synthesis, through chemical and physical methods, requires high temperatures and/or pressures resulting in high energy consumption and the generation of large amounts of waste. In recent years, research into the synthesis of NPs has shifted to more green and biological methods, often using microorganisms. A biological approach has many advantages over chemical and physical methods. Reactions are catalysed in aqueous solutions at standard temperature and pressure (cost effective and low energy syntheses). This method does not require solvents or harmful chemicals, making NP biosynthesis a greener and more eco‐friendly method. Furthermore, NP synthesis by microbes does not require the use of pure starting materials; thus it can simultaneously be used for the bioremediation of contaminated water, land and waste, and the biosynthesis of NPs. Therefore the biosynthesis of NPs contributes to the sustainable development goals, while the alternative physical and chemical methods exclusively utilize scarce and expensive resources for NP synthesis. Nanoparticles are currently being synthesized through chemical and physical methods on an industrial scale. However, these methods of synthesis do not fit with sustainable development goals as they require high temperatures and/or pressures resulting in high energy consumption and the generation of large amounts of waste.
