Abstract

To date, the encapsulation of therapeutic enzymes in a protective matrix is an optimized strategy for the maintenance of their stability, facilitating their clinical application. However, the stability and activity of therapeutic enzymes are often in tension with each other. A rigid protective matrix may effectively maintain the stability of therapeutic enzymes, but it can reduce the diffusion of substrates toward the therapeutic enzyme active site, dramatically affecting their catalytic efficiency. Here, we exploited a kind of nanogels by in situ polymerization on the arginine deiminase (ADI) surface with 3-acrylamido-phenylboronic acid (APBA) monomer. These nanogels efficiently improved the thermal stability (25–75℃), the pH stability (pH 1–13), and protease (trypsin) stability of ADI due to the strong rigidity of the surface poly(APBA) shell. And even after 60 days of storage, ∼60% of the activity of ADI encapsulated by nanogels remained. Furthermore, ADI encapsulated by nanogels could efficiently degrade arginine to increase the ratio of citrulline to arginine in mice plasma. That is because autologous glucose binds with APBA leading to the hydrophilicity increase of nanogels, and then, the arginine molecules can readily diffuse toward the encapsulated ADI. This nanogel platform eases the tension between the stability and activity of therapeutic enzymes. The resulting nanogels can efficiently maintain the in vitro stability and the in vivo activity of therapeutic enzymes, facilitating the exploitation of new therapeutic enzyme formulations, which can be transported and stored in vitro for a long time and be applied effectively in vivo.

Abstract

Immune activation has been widely recognized to promote anti‐tumor effects in vivo. However, in previous anti‐tumor studies of combined photo/immunotherapy, the tumor apoptosis pathway is widely regarded as an independent process, which led to an incomplete understanding of the anti‐tumor mechanisms of the immune system during phototherapy. Herein, the decisive role of immune activation for the anti‐tumor effect of phototherapy and its specific mechanism, are investigated by preparing a melanin@chlorin e6@hyaluronic acid and oxidized Bletilla striata polysaccharide@NO‐donor (MCH‐OBN) nanoplatform, which integrated significant immune activation by phototherapy. The comparison of anti‐tumor effects between wild‐type mice and immunodeficient mice showed that effective phototherapy provided by the MCH‐OBN can not independently kill tumor cells in vivo, as it significantly depends on the immune activation. Furthermore, the activated immune system is demonstrated to destroy the tumor cell "barrier protection" by inhibiting the growth of cancer‐associated fibroblasts (CAFs), thereby ensuring the damage of heat, reactive oxygen species (ROS), and other components of phototherapy to the tumor. Thus, this work reveals for the first time the biological consequences of immune activation that determine the anti‐tumor effect of phototherapy by regulating CAF proliferation, which is of great significance for optimizing anti‐tumor clinical treatments through phototherapy.

Abstract

The research on proximity sensing electronic skin has garnered significant attention. This electronic skin technology enables detection without physical contact and holds vast application prospects in areas such as human‐robot collaboration, human‐machine interfaces, and remote monitoring. Especially in the context of the spread of infectious diseases like COVID‐19, there is a pressing need for non‐contact detection to ensure safe and hygienic operations. This article comprehensively reviews the significant advancements in the field of proximity sensing electronic skin technology in recent years. It covers the principles, as well as single‐type proximity sensors with characteristics such as a large area, multifunctionality, strain, and self‐healing capabilities. Additionally, it delves into the research progress of dual‐type proximity sensors. Furthermore, the article places a special emphasis on the widespread applications of flexible proximity sensors in human‐robot collaboration, human‐machine interfaces, and remote monitoring, highlighting their importance and potential value across various domains. Finally, the paper provides insights into future advancements in flexible proximity sensor technology. [ABSTRACT FROM AUTHOR]

Abstract

Implant‐associated complications arise due to non‐optimized cell–biomaterial interactions. It is well known that cells respond to their physicochemical microenvironment on 2D interfaces and 3D networks. Attempts to manipulate this interaction target surface parameters such as wettability (W), stiffness (S), and topography (T) to influence cell differentiation, adhesion, and morphology, due to induction of gene activation and protein expression. Investigating the combinatorial influence of all three mentioned parameters simultaneously remains challenging, though most realistic, since all three parameters are inherently present on a surface. Herein, a novel high‐throughput screening technology, which allows investigating the cell response of human bone‐marrow‐derived mesenchymal stem cells toward three varying biomaterial surface parameters simultaneously, is presented. The platform provides efficient screening and cell response readout to a vast amount of combined biomaterial surface properties, in a single‐cell experiment. Surface gradients of aligned wrinkle T, S, and W are orthogonally combined giving four combinatorial surfaces. The screening outcome is validated by translating interesting regions to homogeneous surfaces. Cells are found to behave similar to the screening in terms of adhesion, spreading, and vimentin expression. The technology tremendously supports the identification of optimal surface parameter combinations and potentially addressing many of the current implant‐associated complications.
