In the ongoing exploration of therapeutic strategies with improved outcomes and reduced adverse effects, phototherapies (PTs), including photothermal (PTT) and photodynamic therapy (PDT), are gaining attention due to their non-invasive and targeted nature, resulting in reduced side effects. However, further material optimizations are needed to enhance PT performance. Metal-organic frameworks (MOFs) have emerged as promising PTT/PDT nanoplatforms due to their tunable structures, high surface area, and ability to host photoactive agents. Their porous architecture facilitates efficient photosensitizer encapsulation and promotes light-induced thermal effects, improving therapeutic stability and efficacy. The therapeutic potential of MOFs is further enhanced when combined with multiple treatment modalities. This review focuses on the roles of Fe/Cu-based MOFs in PTs, their synthesis, underlying mechanisms in PTT/PDT, and recent design advancements. It also summarizes the progress in Cu/Fe-MOF nanocomposite development over the past 5 years, from construction to synergistic applications.

However, existing virus-based methods for producing cellular products are plagued by high costs, which seriously limit their adoption. In this paper, the development of a mechanical transfection device is described, which passes cells through micron-sized pores and is capable of delivering different molecules into cells. The effects of parameters such as pore size, flow rate, and payload concentration on transfection efficiency are studied and used to inform a standard transfection protocol. Finally, the delivery of CAR-encoding mRNA into primary T-cells is demonstrated to manufacture CAR-T cells, which secrete IFN-γ and TNF-α in an antigen-specific manner.

However, their pleiotropic effects, short half-life, and poor biodistribution have limited their clinical translation. Advances in protein engineering have enabled the design of modified cytokines with enhanced stability, receptor selectivity, and tissue-targeting capabilities, offering new therapeutic opportunities for modulating immune activity and promoting tissue healing. Many of these engineering approaches have been pioneered in cancer immunotherapy, where cytokines are often designed to sustain inflammation and enhance cytotoxic immune responses. In contrast, regenerative medicine usually requires immune resolution, necessitating a distinct and sometimes opposite application of cytokine engineering strategies. This review explores the latest advancements in cytokine engineering for regenerative applications, focusing on strategies to enhance cytokine stability, modulate receptor affinity, improve targeting, and regulate endogenous cytokine signaling. Numerous approaches, highlighting how targeted immune modulation can enhance tissue healing while minimizing fibrosis and chronic inflammation, are discussed. These advances hold great promise for treating chronic wounds, fibrotic diseases, and tissue injuries with limited regenerative capacity, paving the way for precise, effective, and clinically translatable cytokine therapeutics.

This dual-functionalized nanocarrier system achieves an ≈8.5-fold increase in cytotoxicity compared to aptamer-targeted delivery lacking hyaluronidase.
