The emergence of single-atom catalysts offers exciting prospects for the green production of hydrogen peroxide; however, their optimal local structure and the underlying structure-activity relationships remain unclear. Here we show trace Fe, up to 278 mg/kg and derived from microbial protein, serve as precursors to synthesize a variety of Fe single-atom catalysts containing FeNO (1 ≤ x ≤ 4) moieties through controlled pyrolysis. These moieties resemble the structural features of nonheme Fe-dependent enzymes while being effectively confined on a microbe-derived, electrically conductive carbon support, enabling high-current density electrolysis.

A stimuli-responsive drug delivery system is developed for controlled delivery of curcumin (Cur) and chemo-photothermal therapy of breast cancer (BC). Cur is first loaded into mesoporous polydopamine nanoparticles (mPDA NPs) by π-π stacking, and then the Cur loaded mPDA NPs (mPDA NPs@Cur) are encapsulated in the hydrogels prepared through the crosslinking of oxidized konjac glucomannan (oxKGM) and carboxymethyl chitosan (CMCS). Owing to the pH-sensitivity of the hydrogels and the outstanding photothermal conversion capability of mPDA NPs, the release of Cur from the hydrogels can be greatly accelerated in acidic media upon near infrared (NIR) irradiation.

Human succinic semialdehyde dehydrogenase is a mitochondrial enzyme fundamental in the neurotransmitter γ-aminobutyric acid catabolism. It catalyzes the NAD-dependent oxidative degradation of its derivative, succinic semialdehyde, to succinic acid. Mutations in its gene lead to an inherited neurometabolic rare disease, succinic semialdehyde dehydrogenase deficiency, characterized by mental and developmental delay.

In this study, we investigate the electrodeposition of various metals on silicon. Mn, Co, Ni, Ru, Pd, Rh, and Pt were identified as promising candidates for controlled electrodeposition onto silicon. Electrochemical evaluations employing cyclic voltammetry, Scanning Electron Microscopy (SEM) associated with energy-dispersive X-Ray Spectroscopy (SEM-EDS), and X-Ray Photoelectron Spectroscopy (XPS) techniques confirmed the deposition of Pd, Rh, and Pt as nanoparticles.
