MnSO-modified biochar (Mn-BC) was synthesized to remove berberine hydrochloride (BH) from wastewater by utilizing tea waste as raw material and MnSO as modifier. Brunel Emmett Taylor (BET) analysis reveals that the specific surface area (SSA) and average pore size (D) of Mn-BC are 1.4 and 7 times higher than those of pristine biochar apart, attributing to the dissociation effect can promote the dispersion of MnSO in the pores of the biochar. Meanwhile, the doping of Mn not only introduces additional oxygen-containing functional groups (OCFGs), but also modulates the π electron density. Furthermore, Response surface method (RSM) analysis reveals that Mn-BC dosage has the most significant effect on BH removal, followed by BH concentration and pH value. Kinetic and isothermal studies reveal that the BH adsorption process of Mn-BC was mainly dominated by chemical and monolayer adsorption. Meanwhile, density functional theory (DFT) calculations confirm the contribution of Mn doping to the conjugation effect in the adsorption system. Originally proposed Mn-BC is one potentially propitious material to eliminate BH from wastewater, meanwhile this also provides a newfangled conception over the sustainable utilization of tea waste resources.

Three-photon fluorescence (3PF) microscopy encounters significant challenges in biological research and clinical applications, primarily due to the limited availability of high-performance probes. We took a shortcut by exploring the excellent 3PF property of berberine hydrochloride (BH), a clinically utilized drug derived from the traditional Chinese medicine, Coptis. Capitalizing on its renal metabolism characteristics, we employed BH for in vivo 3PF microscopic imaging of the mouse kidney.

In this study, the interactions between three quaternary ammonium salt (QAS) cationic surfactants with different branched-chain lengths (TMBAC, TEBAC, and TBBAC) and DNA are investigated by UV-vis absorption, fluorescence and CD spectroscopy, viscosity method, and gel electrophoresis. Berberine hydrochloride (BR) is utilized as a fluorescent probe. The three interaction modes and strengths are compared.

The development of innovative therapeutic strategies that combine multiple treatment modalities is essential for effective cancer therapy. In this study, we engineered berberine (BER)-loaded mesoporous polydopamine (MPDA) nanoparticles (BER-MPDA) to enhance anti-tumor efficacy through synergistic chemotherapy and photothermal therapy (PTT). The mesoporous structure of MPDA allowed for a high loading capacity of BER, a natural isoquinoline alkaloid with known anticancer properties.
