The effect of lead on dermal exposure of plasticizers in toys and associated risk assessment

open access: yesEmerging Contaminants
Numerous studies reported risk assessment of human exposure to plasticizers in toys through dermal pathways, however, dermal bioaccessibility and percutaneous penetration of plasticizers under effects of lead had been seldom studied. In the present study,

Macrophage Membrane‐Camouflaged Nanozyme Microneedles Restore Immunovascular Homeostasis Through SPP1‐ApoE Signaling in Diabetic Wounds

open access: yesAdvanced Healthcare Materials, EarlyView.
Macrophage membrane‐coated Cu/Zn‐MOF nanozyme microneedles (MNs) reprogram the diabetic wound microenvironment through localized, minimally invasive delivery. By suppressing M1‐like macrophage activation while promoting extracellular matrix deposition and angiogenesis, this biomimetic platform accelerates diabetic wound repair.
