Optical sensors continue to demonstrate tremendous potential across a wide range of applications due to their high versatility and low cost. This feature article will focus on a number of recent advances made in improving the performance of extraction-based optical ion sensors within our group. This includes the progress of anchored solvatochromic transduction to provide pH and sample volume independent optical responses in nanoemulsion-based sensors. A recent breakthough is in polyion sensing in biological fluids that uses a novel indirect transduction mechanism that significantly improves the selectivity of dinonylnaphthalenesulfonate-based protamine sensors and its potential applications beyond polyion sensing. The role of particle stabilizers in relation to the response of emulsified sensors is shown to be important. Current challenges in the field and possible opportunities are also discussed.
由于其多功能性和低成本，光学传感器在广泛的应用中继续展示出巨大的潜力。本文将重点介绍我们小组在提高基于萃取的光学离子传感器性能方面的一些最新进展。这包括锚定溶致变色转导在基于纳米乳液的传感器中提供 pH 值和样品体积独立光学响应的进展。最近的突破是在生物流体中的聚离子传感中，使用了一种新的间接转导机制，显著提高了基于二壬基萘磺酸钠的鱼精蛋白传感器的选择性及其在聚离子传感之外的潜在应用。还表明，颗粒稳定剂与乳化传感器响应之间的关系很重要。目前该领域面临的挑战和可能的机遇也进行了讨论。
