A large range of nanoparticles have been developed to encapsulate hydrophobic drugs. However, drug loading is usually less than 10 % or even 1 %. Now, core-shell are fabricated having exceptionally high up 65 (drug weight/the total weight drug-loaded nanoparticles) and encapsulation efficiencies (>99 %) based on modular biomolecule templating. Bifunctional amphiphilic peptides designed not only stabilize but also induce biosilicification at the nanodrug particle surface thus forming drug-core silica-shell nanocomposites. This platform technology highly versatile for encapsulating various cargos. Furthermore, lead better in vitro cytotoxic effects vivo suppression tumor growth, highlighting significance using drug-loading nanoparticles.

Over the past several decades, rapid advances have been made in application of nanomaterials biomedical field including bioimaging and drug delivery. Owing to natural biocompatibility, diverse design, dynamic self-assembly, peptides can be used as modules construct self-assembled peptide-based nanomaterials, which a high potential reducing toxicity, improving targeting, enhancing delivery efficiency. In this review, three typical design strategies peptide for summarized ex situ construction, morphological transformation, construction systems (PDDs). Drugs loaded by physical encapsulation or chemical conjugation methods, showing enhanced retention effects at tumor sites increase uptake rate drugs. Interestingly, drug-free also nanomedicines These implicate bright prospect intelligent nanomedicine clinical translation.

Drug-loading hydrogels are promising candidates in the bioengineering research field; nevertheless, hydrophobic drug loading into a hydrophilic carrier system remains unsolved and is full of challenges. In this work, following potential dual interactions between peptides aromatic drugs, we developed potent hybrid hydrogel formation method, namely, "peptide-/drug-directed self-assembly". The were synthesized using polyethylene glycol (PEG)-based Fmoc-FF peptide polyurethane, which curcumin could be encapsulated through self-assembly with via π-π stacking. On basis this, capacity improved to as high 3.3 wt % sustained release. addition, enhanced mechanical properties from 4 kPa over 10 kPa, similar that natural soft tissues. Furthermore, injectable self-healing since peptide/curcumin coassembly was noncovalent reversible. Spectroscopy results confirmed existence peptide/curcumin. Further vivo experiments effectively demonstrated improve cutaneous wound healing full-thickness skin defected model. This peptide-/drug-directed polyurethane used platform for tissue-engineering scaffold biomedical application.

Supramolecular nanomaterials as drug carriers have recently received increasing attention due to their intrinsic merits such high stability, strong inclusion capability, and facile modification of the parental structure; however, intelligent ones with combined capacities long blood circulation, highly efficient tumor cell uptake, site-oriented release inside cells are still rather limited. Herein, we report a strategy using supramolecular aggregation-induced emission (AIE) nanodots for image-guided delivery, which integrate both advantages AIE nanomaterials. The dots prepared by host-guest coassembly matrix metalloproteinase-2 (MMP-2) sensitive PEG-peptide (PEG2000-RRRRRRRR (R8)-PLGLAG-EKEKEKEKEKEK (EK6)) functional α-cyclodextrins (α-CD) derivatives that conjugated anticancer gemcitabine (GEM) far-red/near-infrared fluorescent rhodanine-3-acetic acid-based luminogen, respectively. realize circulation time virtue zwitterionic stealth peptide EK6. After largely accumulating in tissues enhanced permeability retention effect, can successively respond tumor-overexpressed MMP-2 intracellular reductive microenvironment, achieving cancer cellular uptake selective GEM within cells, thus exhibit excellent inhibition ability subcutaneous orthotopic pancreatic models.
