Drugs need to be formulated into medicines before they can be given to patients in a useful form. Injections are an important group of formulations and their viscoelasticity, that is, the ease in which the fluid can be deformed as it passes through the syringe, is an important consideration. However, bulk testing of the viscoelastic behaviour of injectables is often not feasible since they are available only in limited amounts. Here we will investigate new techniques in the field of microrheology, which have been demonstrated to measure the viscoelasticity of very small volumes of sample. The volumes that can be measured are so small that the technique can be applied to the measurement of the viscoelasticity of sub-cellular compartments such as the nucleus and mitochondria. Therefore, in addition to addressing the key issue of pharmaceutical formulation the work will also attempt to measure changes in the viscoelastic environment of a drug as it is internalised into a cell via a process known as endocytosis.

药物需要被制成药物，然后才能以有用的形式提供给患者。注射剂是一组重要的制剂，它们的粘弹性，即液体通过注射器时容易变形的程度，是一个重要的考虑因素。然而，对注射剂的粘弹性行为进行批量测试通常是不可行的，因为它们只有有限的量。在这里，我们将研究微观流变学领域的新技术，这些技术已经被证明可以测量非常小体积样品的粘弹性。可测量的体积如此之小，以至于该技术可以应用于测量亚细胞隔间的粘弹性，如细胞核和线粒体。因此，除了解决药物配方的关键问题外，这项工作还将试图测量药物通过内吞作用进入细胞时粘弹性环境的变化。
