LAP also absorbs at 365 nm, but the molar extinction coefficient is lower than its characteristic peak at 384 nm. This means you may need to slightly increase the concentration or exposure time. Therefore, unless limited by equipment, please stick to a 405 nm light source.\r\n<h3><strong><b>IV.

However, based on discussions with my colleagues, the next frontier may be &#8220;dynamic photocuring.&#8221;\r\n\r\nCurrently, we use one-time, irreversible curing. But in the future, will it be possible to develop photoinitiator systems that respond to specific wavelengths (such as far-red light or two-photon excitation), and whose curing degree or mechanical properties can be &#8220;adjusted on demand&#8221; or &#8220;locally erased&#8221;? Imagine printing a cardiac patch and then being able to remotely and gradually adjust its hardening process using non-invasive deep-tissue light to better match the growth rhythm of the native tissue. This might require entirely new molecular designs, such as coupling LAP&#8217;s photosensitive groups with reversible reaction\r\n\r\n<strong><b>V\u00e9gezet\u00fcl szeretn\u00e9m feltenni ezt a k\u00e9rd\u00e9st:<\/b><\/strong>\u00a0Melyek a legnagyobb kih\u00edv\u00e1sok, amelyekkel a LAP haszn\u00e1lata sor\u00e1n tal\u00e1lkozott a konkr\u00e9t kutat\u00e1s vagy alkalmaz\u00e1s sor\u00e1n?
