Recently, we have been developing novel fluorescence probes, focusing on two photon absorbing materials as well as bio- and nano materials. After synthesizing bioconjugated molecules of therapeutic activity and nano biosensors for early diagnosis of disease, we look for application of bio-imaging and disease diagnosis.
