Photoresponsive liposome development is needed to serve as a facile alternative to ELISA which is ineffective for detecting small levels of biomarkers due to low detection sensitivity. The US20210396744 patent application outlines novel photoresponsive liposomes for the detection of target substances with the aid of light. Although versatile, there may be possible stability issues that can be avoided with the appropriate selection of liposome components. Furthermore, the clinical success of this technology depends on many parameters like plasma stability, efficient loading of photosensitive components in the membrane, and immobilization of molecular recognition elements to the membrane. Despite several challenges, they possess enormous potential to become a non-invasive tool for the detection of target substances.
