Abstract:
Semiconductor nanoparticles have rapidly found a broad range of applications as optical imaging
agents. The presented paper describes the growth, analysis of optical spectra and study of cellular
imaging of Mn-doped cadmium sulfide nanoparticles. Semimagnetic semiconductor nanoparticles
CdMnS are characterized by high brightness, improved photostability and multicolor size- and
structure-dependent light emission in the visible range of spectra. They are emerging as a new
class of fluorescent reporters with properties and applications that are not available with traditional
organic dyes. In order to obtain nanosensors different surfactants, growth factors and conditions
such as surfactant concentrations, ionic strength, precursor concentration have been varied. Formation
of nanoparticles was monitored by optical methods. The average nanoparticle size was
estimated by optical spectra. For cellular research histological section of a placental tissues and
liver tissues has been used. This procedure is possible only after cell fixation and permeabilization
treatment is needed to allow the nanosensors to enter inside the cell.
