Magnetic-fluorescent nanoparticles can offer various applications such as imaging, labeling, separation, and therapy. Here we have functionalized magnetic nanoparticle (MNP) with fluorescent dyes such as acridine orange (ACO) and rhodamine-B (RHB) via chemical crosslinkers. The fluorescent MNPs were characterized by TEM, SQUID, and FTIR to prove the successful conjugation. Fluorescent spectrosc...
