Description

Application

<ul>
<li><strong>Dual Fluorescence Bioimaging:</strong> N,N-Dimethylaniline derivatives to develop NIR-II emissive donor-acceptor-donor fluorophores. These compounds are used for dual fluorescence bioimaging and photothermal therapy applications, illustrating the critical role of N,N-Dimethylaniline in the development of new biomedical imaging agents (Sparks et al., 2024).</li>
<li><strong>Real-Time Monitoring of Biomolecules: </strong>Dimethylaniline is used in the construction of a fluorescent probe for in vivo real-time imaging and inhibition of A and beta;-fibril formation (Chen et al., 2024).</li>
<li><strong><strong>Photoinduced Electron Transfer Studies: </strong></strong>N,N-dimethylaniline is used in the quenching of the S1 state of two polar dyes, coumarin 152a and Nile red (Verma et al., 2024).</li>
