The combination of nanotechnology and chemotherapy has resulted in more effective drug design via the development of nanomaterial-based drug delivery systems (DDSs) for tumor targeting. Stimulus-responsive DDSs in response to internal or external signals can offer precisely controlled delivery of preloaded therapeutics. Among the various DDSs, the photo-triggered system improves the efficacy and safety of treatment through spatiotemporal manipulation of light. Additionally, pH-induced delivery is one of the most widely studied strategies for targeting the acidic micro-environment of solid tumors. Accordingly, in this review, we discuss representative strategies for designing DDSs using light as an exogenous signal or pH as an endogenous trigger.

: The emergence of nanoscale drug delivery systems provides new opportunities for targeting delivery of chemotherapeutic drugs and has achieved excellent results. In recent years, with the arising of the concept of intelligent drug delivery systems, the design and preparation of carriers have become more and more complicated, which is not conducive to clinical transformation. Researchers are gradually focusing on biomimetic nanoscale drug delivery systems, trying to combine the physicochemical properties of nanoscale carriers with the natural biological functions of endogenous substances, so as to boost tumor targeting delivery. In this article, we first classify and introduce biomimetic nanoscale drug delivery systems, and then emphasize their unique biological functions. The biomimetic nanoscale drug delivery systems have the advantages of simple preparation, powerful functions, and low immunogenicity, having a good application prospect.

Combination of nanotechnology, biochemistry, chemistry and biotechnology provides the opportunity to design unique nanoparticles for tumor targeting, drug delivery, medical imaging and biosensing. Nanoparticles conjugated with biomolecules such as antibodies, peptides, vitamins and aptamer can resolve current challenges including low accumulation, internalization and retention at the target site in cancer diagnosis and therapy through active targeting. In this review, we focus on different strategies for conjugation of biomolecules to nanoparticles such as inorganic nanoparticles (iron oxide, gold, silica and carbon nanoparticles), liposomes, lipid and polymeric nanoparticles and their application in tumor targeting.

AbstractComplex biological tissues are highly viscoelastic and dynamic. Efforts to repair or replace cartilage, tendon, muscle, and vasculature using materials that facilitate repair and regeneration have been ongoing for decades. However, materials that possess the mechanical, chemical, and resorption characteristics necessary to recapitulate these tissues have been difficult to mimic using synthetic resorbable biomaterials. Herein, we report a series of resorbable elastomer-like materials that are compositionally identical and possess varying ratios of cis:trans double bonds in the backbone. These features afford concomitant control over the mechanical and surface eroding degradation properties of these materials. We show the materials can be functionalized post-polymerization with bioactive species and enhance cell adhesion. Furthermore, an in vivo rat model demonstrates that degradation and resorption are dependent on succinate stoichiometry in the elastomers and the results show limited inflammation highlighting their potential for use in soft tissue regeneration and drug delivery.
