Several nanomaterials rely on the passive accumulation in the neoplasm target because of enhanced permeability and retention effect. On the other lhand, directing nanomaterials to the target by employing the targeting agents may lead to a pivotal improvement in the efficacy of the treatment fora number of cancers. However, targeting moieties often lose their functionality upon injection in the bloodstream, leaving questions on their efficiency. Here, we assessed using a significant in vitro 3D model of pancreatic carcinoma the targeting efficiency of passion fmit-like nano architectures (NAs) incorporated with a peptide that can recognize transferrin directly in the medium, thereby modulating protein salvation. NAs are biodegradable ultrasmall-in-nano platforms that combine the most appealing behaviors of noble metal nanomaterials with organism excretion of the building blocks by the renal pathway. Although the confocal images significantdid not illustrate the targeting efficiency of the peptide-modified NAs, an improved internalization was quantitatively observed by inductively coupled plasma-mass spectrometry analysis. Our findings deffionstrate that the peptide conjugation of NAs might be considered to enhance their theranostic potentials for this type of neoplasm.
