Keeping things clean requires large amounts of energy, everyone on the planet uses energy to keep cloths clean and this puts a huge demand on the environment. Current cleaning detergents are a complex chemical and biological components, but in terms of their cleaning composition but can broadly be considered to contain (i) surfactants to solubilise fabric-based stains; (ii) enzymes to digest stains and (iii) bleaches to degrade and increase the hydrophillicity of coloured stains. In this project we use an atomic force microscope to study how individual enzymes digest stains. The atomic force microscope will measure the interaction strength between an enzyme and an oil surface. Once we have an understanding of this process we will use this knowledge to modify the enzymes in order to allow them to work at lower temperatures. These modified enzymes will be studied using the atomic force microscope under the conditions the enzymes would face in a typical washing cycle, this will allow us to further improve the efficiency of the enzyme.

保持清洁需要大量的能量，地球上的每个人都使用能量来保持衣服清洁，这对环境产生了巨大的需求。当前的清洁洗涤剂是一种复杂的化学和生物学成分，但就其清洁成分而言，可以广泛地认为包含（i）表面活性剂以溶解基于织物的污渍； （ii）酶消化污渍和（iii）漂白剂以降解和增加彩色污渍的亲水性。在这个项目中，我们使用原子力显微镜研究各个酶如何消化污渍。原子力显微镜将测量酶和油面之间的相互作用强度。一旦我们了解了这一过程，我们将使用此知识来修改酶，以便它们在较低的温度下工作。这些修饰的酶将在酶在典型的洗涤周期中面临的条件下使用原子力显微镜进行研究，这将使我们能够进一步提高酶的效率。
