WebIn this current work, the UV-cured FSG hybrid process was modified for 2PA polymerization by adding a suitable 2PA photoinitiator, 7-Diethylamino-3-thenoylcoumarin (DETC) [17]. The current solgel ... Weblithography has only been shown with a single photoinitiator, namely 7-diethylamino-3-thenoylcoumarin (DETC) (Figure 1c).6,19−21 Alternative STED-related techniques use other photoinitiators but still rely on (meth)acrylates as the photoresist. This severely restricts a covalent and targeted attachment of molecules (such as proteins) or ...
WebDec 7, 2024 · For the first-time 7-Diethylamino-3-thenoylcoumarin (DETC) is used as the photoinitiator. Only 0.5 wt% of DETC was required to promote both polymerisation and photoreduction of up to 20 wt% of ... We would like to show you a description here but the site won’t allow us. WebThe amount of activated photo initiator depends on the concentration of photoinitiator in the material, the number of photons to which the material is exposed and the energy of the photons (wavelength), the latter depending on the curing light.The most common photoinitiator in dental materials today is camphorquinone, which has a peak activity ...
