Using the cytomembranes (FMs) of hybrid cells acquired from fusion cancer and dendritic (DCs), this study offers a biologically derived platform for combination immunotherapy traditional oncotherapy approaches. Due to immunoactivation implicated in cellular fusion, FMs can effectively express whole antigens immunological co-stimulatory molecules robust immunotherapy. share tumor's self-targeting character with parent cells. In bilateral tumor-bearing mouse models, FM-coated nanophotosensitizer causes durable immunoresponse inhibit rebound primary tumors post-nanophotosensitizer-induced photodynamic therapy (PDT). The FM-induced displays ultrahigh antitumor effects even comparable that PDT. On other hand, PDT toward enhances immunotherapy-caused regression irradiation-free distant tumors. Consequently, both are almost completely eliminated. This tumor-specific immunotherapy-based nanoplatform is potentially expandable multiple tumor types readily equipped diverse functions owing flexible nanoparticle options.

Natural polyphenols have attracted great interests in medicine, food and cosmetics due to their versatile functions such as antioxidant, anticancer antibacterial. The polyphenolic structures (i.e. catechol, pyrogallol) natural are responsible for strong noncovalent interactions via multiple hydrogen bonding hydrophobic interactions, dynamic covalent complexation with boronate groups metal ions. In this review, we focused on the preparation applications of polyphenol-based coating films, nanoparticles, nanocapsules, hydrogels emerged from chemical functional signatures. beneficial role mechanism facilitating delivery proteins, nucleic acids conventional drug molecules were reviewed. Finally, challenges systems perspectives rational design next generation polyphenol biomaterials will be discussed.

Magnetic microrobots can be actuated in fuel-free conditions and are envisioned for biomedical applications related to targeted delivery therapy a minimally invasive manner. However, mass fabrication of with precise propulsion performance excellent therapeutic efficacy is still challenging, especially predictable controllable Herein, we propose facile technique production magnetic multiple functions using Spirulina ( Sp.) as biotemplate. Core-shell-structured Pd@Au nanoparticles (NPs) were synthesized Sp. cells by electroless deposition, working photothermal conversion agents. Subsequently, the Fe3O4 NPs deposited onto surface obtained (Pd@Au)@ particles via sol-gel process, enabling them magnetically actuated. Moreover, anticancer drug doxorubicin (DOX) was loaded on (Pd@Au)/Fe3O4@ microrobots, which endows additional chemotherapeutic efficacy. The as-prepared biohybrid Sp.-DOX not only possess efficient highest speed 526.2 μm/s under rotating field but also have enhanced synergistic chemo-photothermal Furthermore, they structurally disassembled into individual near-infrared (NIR) laser irradiation exhibit pH- NIR-triggered release. These intriguing properties enable very promising platform loading, delivery, therapy.
