Despite the promise of PTT, the clinical translation of many nanomaterial-based photothermal agents is impeded by intrinsic toxicity and insufficient tumor specificity. Moreover, off-target biodistribution of photosensitizers after systemic administration can increase systemic exposure, reduce tumor delivery, and ultimately compromise therapeutic efficacy, underscoring the need for advanced material delivery concepts that enhance selective tumor accumulation and therapeutic outcome. Here, we present a targeted MXene-based PTT platform designed to address these challenges. Among the tested MXenes (Ti<sub>3</sub>C<sub>2</sub>, Nb<sub>2</sub>C, and V<sub>2</sub>C), Ti<sub>3</sub>C<sub>2</sub> was identified as the most biocompatible and safest candidate, demonstrating minimal cytotoxicity, negligible impact on cell-cycle progression, and no significant impairment of long-term proliferative capacity. Ti<sub>3</sub>C<sub>2</sub> MXene was subsequently coated with polydopamine (PDA) and conjugated to an anti-human-CEACAM1 (hCC1) antibody (Ab) to enable antigen-dependent tumor targeting. In a murine melanoma model bearing human CC1-positive (hCC1+) and CEACAM1-negative (hCC1-) tumors, we evaluated the outcomes of both intravenous (IV) and intratumoral (IT) administration of the Ti<sub>3</sub>C<sub>2</sub>-PDA-anti-hCC1 nanoconjugate. Quantification of titanium by inductively coupled plasma atomic emission spectrometry (ICP-AES), in combination with histological analysis, revealed preferential accumulation of the targeted nanoconjugate in hCC1+ tumors compared with hCC1- controls. Notably, after IV delivery, Ti<sub>3</sub>C<sub>2</sub>-PDA-anti-hCC1 conjugate demonstrated enhanced deposition in the tumor and lower non-specific uptake in clearance organs, including the liver, lungs, and spleen, compared with non-antibody-functionalized MXene.

Immunoengineering, broadly defined as the strategic design and manipulation of immune responses, has emerged as an interdisciplinary field integrating immunology, materials science, and biomedical engineering, enabling substantial advances in the precise modulation of immune function. However, conventional immunomodulatory materials-such as synthetic polymers, nanoparticles, and biologically derived matrices-generally function as passive platforms, with limited capacity to dynamically adapt to complex and evolving pathological microenvironments. To address these limitations, living biomaterials have emerged as a transformative paradigm. Among them, microalgae represent a particularly promising and versatile platform, owing to their intrinsic photosynthetic oxygen-generating capability, diverse production of bioactive metabolites, favorable biocompatibility, scalability, and amenability to genetic engineering. Microalgae can alleviate hypoxia, modulate inflammatory signaling pathways, and produce antioxidant and anti-inflammatory metabolites as well as extracellular vesicles, thereby enabling cross-kingdom communication with host systems. Recent advances have further demonstrated their integration with polymers, nanomaterials, and microbial systems to construct multifunctional biohybrid platforms for active and adaptive immune modulation. Despite rapid progress, the field remains fragmented, and a systematic framework for translating microalgae-based living biomaterials into immunomodulatory therapies is still lacking. This review provides a comprehensive overview of microalgae-derived living biomaterials for immunoengineering, including their fundamental biological characteristics and mechanisms of immune regulation, key engineering strategies (such as encapsulation, biohybridization, and genetic engineering), and emerging therapeutic applications.

This review provides a mechanistic and translational analysis of injectable nanocomposite (NC) hydrogels, systematically examining how nanoparticle-polymer interfacial interactions govern gelation kinetics, mechanical properties, and controlled therapeutic release. Unlike previous reviews focused on material cataloguing, we critically evaluate the distinctive advantages of NC hydrogels over conventional dynamic hydrogels; including hierarchical drug release profiles, enhanced tumour penetration, and multiscale environmental responsiveness; whilst providing evidence-based assessment of clinical translation pathways. The strategic incorporation of metal-based nanostructures, carbon nanomaterials, lipid carriers, and black phosphorus nanosheets is analysed across four key biomedical domains: advanced drug delivery systems, tissue engineering scaffolds, chronic wound healing platforms, and biosensing technologies. We provide systematic coverage of injectability parameters, smart responsive behaviours, and patient-specific customisation strategies essential for minimally invasive delivery. Critically, this review addresses the gap between preclinical promise and clinical reality by examining actual clinical trial data, regulatory challenges, and manufacturing scalability barriers. Emerging artificial intelligence and machine learning tools for accelerated NC hydrogel design, predictive modelling, and real-time therapeutic monitoring are evaluated as enabling technologies for next-generation precision biomedicine.
