To address this gap, aptamers have found an important application in the recognition of tumor biomarkers such as mucin 1 (MUC1). However, there are still some difficulties in the use of aptamer, as their rapid biological clearance makes their use as drugs limited. In this study, the anti-MUC1 aptamer was used as a drug delivery system (DDS) for a radioactive polymeric nanoparticle (NP) in the imaging of TNBCs. Thus, poly(lactic-co-glycolic acid) NPs loaded with the anti-MUC1 aptamer and labeled with technetium-99m were used for a biodistribution study and imaging of TNBC. The results confirmed that the NP was successfully obtained, with a mean size of 262 nm, according to the dynamic light scattering data. The biodistribution assay in induced animal models with TNBC showed that although there was a high capture by intestine (>30%), the DDS developed had a high tumor uptake (5%) and with great in vivo imaging properties, corroborating the possibility of use of this DDS as an imaging drug for TNBC.
