Abstract:
H ypocre llin encapsu lated in titanium d iox ide nanopartic les w ere prepared by so-l g el m ethod. The TEM and g rading analysis technique w ere used to investiga te the surface m orphology and the g ra in d iam eter o f the resultant nanopa rtic les. A un iform core she ll struc turew ith m id-d iam eter o f 120 nm w as clearly obse rved. The nanopartic les were characterized w ith UV-v is and FL techn iques. The results suggested tha t hypocre llin has been successfu lly encapsu la ted in titan ium d iox ide nanopartic le, and nanoshells d isp lay a strong absorption w ith bathochrom ic sh ift fo rUV-v is spectra and increased FL intensity, compar ing w ith hypoc re llin in the aqueous so lution. The hypocrellin w as entrapped in T iO2, thus it w ill be bene fic ia l to the app lica tion in pho todynam ic treatm ent.
