Abstract Novel strategies to facilitate tumor‐specific drug delivery and restore immune attacks remain challenging in overcoming the current limitations of chemoimmunotherapy. An antitumor chemoimmunotherapy system comprising bioorthogonal reaction‐ready group tetrazine (TZ) modified with an anti‐PD‐L1 antibody (αPD‐L1 TZ ) TZ‐activatable prodrug vinyl ether‐doxorubicin (DOX‐VE) for self‐reinforced anti‐tumor is proposed. The αPD‐L1 effectively disrupts PD‐L1/PD‐1 interaction activates DOX...

The degradation of oncoproteins mediated by proteolysis-targeting chimera (PROTAC) has emerged as a potent strategy in cancer therapy. However, the clinical application PROTACs is hampered challenges such poor water solubility and off-target adverse effects. Herein, we present an ultrasound (US)-activatable PROTAC prodrug termed NP

Abstract Precise control over drug release rates is critical for enhancing therapeutic efficacy, reducing side effects, and maintaining stable levels. While microneedles (MNs) offer a promising approach transdermal delivery, conventional passive‐response systems often lack adaptability across diverse drugs disease models, limiting their versatility. Here, this work presents flexible bioelectronic microneedle patch (FBMP) that integrates electronics actively controlled delivery. The FBMP...

This paper presents a novel fixed time sliding mode disturbance observer (FTSMDO) based second-order control (FTSMC) for small scale unmanned helicopter to do hover operations in the presence of external disturbances. Sliding is insensitive matched uncertainties but sensitive mismatched uncertainties. The FTSMDO exactly estimates total effecting performance. To counter new surface augmented by approximated defined. FTSMC forces system states reach and then on exponentially converge desired...

Chemotherapy is the primary treatment option for pancreatic cancer, although nanocarrier-based drug delivery systems often struggle with multiple physiological barriers, limiting their therapeutic efficacy. Here, we developed a pH/reactive oxygen species (ROS) dual-sensitive self-adaptive nanocarrier (DATCPT) encapsulating camptothecin (CPT), an analog of chemotherapeutic irinotecan (CPT-11), to enhance chemotherapy outcomes in orthotopic cancer by addressing barriers. The features...
