The important role of gasotransmitters in physiology and pathophysiology suggest employing gasotransmitters for biomedical treatment. Unfortunately, the difficulty in storage and controlled delivery of these gaseous molecules hindered the development of effective gasotransmitters-based therapies. The design of a safe, facile, and wide-scale method to delivery multiple gasotransmitters is a great challenge. Herein, we use an ultrasonic assisted preparation γ-cyclodextrin metal organic framework (γ-CD-MOF) as a broad-spectrum delivery vehicle for various gasotransmitters, such as SO, NO, and HS. The release rate of gasotransmitters could be tuned by modifying the γ-CD-MOF with different Pluronics. The biological relevance of the exogenous gasotransmitters produced by this method is evidenced by the DNA cleavage ability and the anti-inflammatory effects. Furthermore, the γ-CD-MOF composed of food-grade γ-CD and nontoxic metal salts shows good biocompatibility and particle size (180 nm). Therefore, γ-CD-MOF is expected to be an excellent tool for the study of co-delivery and cooperative therapy of gasotransmitters.

Transient electronics are emerging as a promising class of devices designed to disappear after a defined operational period, addressing growing concerns over sustainability and long-term biocompatibility. Built from biodegradable materials that undergo hydrolysis or enzymatic degradation, these systems are particularly well suited for temporary implantable applications, such as neural monitors, wireless stimulators, and drug delivery vehicles, as well as environmentally benign electronics for soil or aquatic disposal. Despite their potential, key challenges remain in expanding the material set for diverse functionalities, achieving high-density integration for advanced operations, and enabling precise lifetime control through strategies such as protective encapsulation.

Targeted drug delivery significantly enhances therapeutic efficacy across various diseases, particularly in cancer treatments, where conventional approaches such as chemotherapy and radiotherapy often cause severe side effects. In this context, nucleic acid aptamers-short, single-stranded DNA or RNA oligonucleotides capable of binding specific targets with high affinity-have emerged as promising tools for precision drug delivery and therapy. Aptamers can be selected against whole, living cells using SELEX and chemically modified for diverse applications.

Harnessing the significant buildup of lactic acid (LA) within the tumor microenvironment (TME) for metabolic manipulation presents a promising avenue for cancer treatment. Nevertheless, single-agent therapies often fail to address the complex and varying needs of TME heterogeneity, posing a substantial scientific hurdle in oncology. In this context, we employ asymmetric mesoporous silica nanoparticles (AMS NPs) as delivery vehicles, simultaneously loading them with zinc‑cobalt‑manganese ferrite nanoparticles (ZCMF NPs), lactate oxidase (LOX), and doxorubicin (DOX).

The retinol isotope dilution (RID) test is the most sensitive method to assess vitamin A status by estimating total liver reserves, considered the reference standard. For gas chromatography-combustion-isotope ratio mass spectrometry detection, C is added to the retinol moiety. The synthetic procedure for C-retinyl acetate begins with the naturally occurring β-ionone.

Bispecific T-cell engagers (BiTEs) are small-molecule antibodies that exhibits potent tumoricidal activity but suffer from a short plasma half-life. Mesenchymal stromal cells (MSCs) represent promising delivery vehicles for sustained therapeutic protein expression. In this study, we used human umbilical cord blood-MSCs (hUC-MSCs) as a delivery system to to secrete HER2/CD3 BiTE antibodies, thereby addressing the pharmacokinetic limitations of conventional BiTE therapies.
