Abstract

Construct a Her-2 nanobody modified nanoplatform as a versatile carrier of cisplatin and evaluate its anti-tumour effects. Size, morphology, cellular uptake, in vitro release, cell viability, bio-distribution and antitumor efficacy were respectively measured by dynamic light scattering, transmission electron microscopy, confocal microscopy, HPLC, MTT assay, ICP-Mass and tumour volume. Nb-CDDP NPs was prepared with average diameter 60.4 ± 8.4 nm, PDI 0.2 ± 0.02, Zeta potential -35.74 mV, entrapment efficiency 89.5%±0.8% and drug loading 28.7%±1.3% (w/w). From which cisplatin could release more rapidly in acidic solution. NPs could be easily phagocytised and exhibited stronger cytotoxic effect in HCT-116 cells with IC₅₀ 1.46 ± 0.019 μg/mL. The concentration of Nb-CDDP NPs in tumour and its inhibition ratio on tumour volume were both higher than without Nb modification, with hardly any influence on body weight. This cisplatin nanoplatform exhibits exceptional properties and high targeting anti-tumour efficacy in colon cancer cells and mice, which maybe provide a promising strategy for precise chemotherapy.

期刊介绍： The Journal of Microencapsulation is a well-established, peer-reviewed journal dedicated to the publication of original research findings related to the preparation, properties and uses of individually encapsulated novel small particles, as well as significant improvements to tried-and-tested techniques relevant to micro and nano particles and their use in a wide variety of industrial, engineering, pharmaceutical, biotechnology and research applications. Its scope extends beyond conventional microcapsules to all other small particulate systems such as self assembling structures that involve preparative manipulation. The journal covers: Chemistry of encapsulation materials Physics of release through the capsule wall and/or desorption from carrier Techniques of preparation, content and storage Many uses to which microcapsules are put.
