Abstract

The size of nanoparticles plays a key role in utilizing enhanced permeability and retention (EPR) effect of tumor, where large-sized nanoparticles possess good retention but poor penetration, while small-sized nanoparticles are on the contrary. Although size-reducible nanoparticles have been designed to partially overcome this dilemma, the initial size and complicated tumor microenvironment remain restricting the tumor distribution of nanoparticles. Herein, we employed tumor-specific CD44 targeted, hyaluronidase-degradable hyaluronic acid (HA) and small-sized, renal-clearable, red emission, cationic bovine serum albumin-protected gold nanocluster (AuNC@CBSA) to successfully construct size-reducible nanoplatform (AuNC@CBSA@HA). By changing the ratio of HA and AuNC@CBSA, different initial sizes of AuNC@CBSA@HA were prepared and their tumor targeting efficiencies, pharmacokinetic profiles were evaluated. Then 200 nm of AuNC@CBSA@HA with optimal EPR effect was screened out to further load paclitaxel (PTX) and indocyanine green (ICG) for chemo- photothermal therapy and nitric oxide (NO) for modulating tumor microenvironment and enhancing drug delivery. The AuNC@CBSA-PTX-ICG@HA-NO 3 showed size-reducible ability under triggering by hyaluronidase and high accumulation in breast cancer with homogenous intra-tumor distribution, suppressed 95.3% of in-situ tumor growth and inhibited 88.4% of lung metastasis growth. In conclusion, we provide a strategy that fully satisfied the concerns in drug delivery to tumor for improved antitumor effect.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
