Optical tweezers can now be regarded as a mature technology. Optical sorting on the other hand is a relatively new development and there is still a lot of potential for improvement. As we have seen, a number of techniques to sort biological cells are already available. While some of these systems are extremely advanced and very good at what they are designed to do, they all come with their own set of disadvantages. As a result, there are possible scenarios in which optical sorting may be the best solution.
