Researchers have extensively investigated photosensitizer (PS) derivatives for various applications due to their superior photophysical and electrochemical properties. However, inherent problems, such as instability and self-quenching under physiological conditions, limit their biological applications. Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) represent two relatively new material types. These materials have high surface areas and permanent porosity, and they show a tremendous deal of potential for applications like these. This review summarizes key synthesis processes and highlights recent advancements in integrating PS-based COF and MOF nanocarriers for biomedical applications while addressing potential obstacles and prospects.

In this study, we construct a quantum well effect-based two-dimensional Z-scheme superlattice heteronanostructure photocatalyst constructed from hydrogen-bonded porphyrin organic frameworks (HOFs) and carbon nitride. Porphyrin HOFs extend spectral absorption, while their π-conjugation and electron density variations significantly enhance charge separation and exhibit favorable alignment with the energy levels of carbon nitride, thereby enabling efficient charge transfer. Carboxylic acid channels in the HOFs further promote the decomposition of water molecules, thereby boosting hydrogen production.

Biomolecule-engineered metal-organic frameworks (Bio-MOFs) are designed by incorporating biomolecules into or onto MOFs through covalent and non-covalent interactions. These composite frameworks exhibit unique catalytic and biological activities, making them highly suitable for various biocatalytic applications. In this review, we highlight recent advances in the material design, bioengineering methods, structural and functional regulation techniques, and biocatalytic applications of Bio-MOFs.

A covalent organic framework TPB-DMTP was physically coated onto the gully-like surface of stainless-steel fiber. The fabricated TPB-DMTP-coated stainless-steel fiber was used to extract five phthalic acid esters (PAEs) prior to the GC-FID separation and determination in bottled tea beverages. The developed SPME-GC-FID method gave limits of detection (S/N = 3) from 0.

In this paper, a novel robust TFPA-TTA-COF coating with nano pores was grafted to the gully-like surface of stainless steel fibers (GS-SSF). The GS-SSF were prepared using a two-step electrochemical etching method, and the covalent organic framework (COF) TFPA-TTA-COF coating was chemically bonded to the gully-like surface via in situ growth. The prepared metal fibers were applied as the headspace solid-phase microextraction (HS-SPME) fibers and combined with gas chromatography (GC) to develop a detection method for phenolic compounds (PCs) in water.
