Inhibitory activity of fibrin-collagen substance (FCS) impregnated by various antibacterial agents against various microorganisms was investigated. It was demonstrated that antibacterials bind well with FCS, providing its sufficient antibacterial activity. Determination of growth-inhibition zones showed that antibacterial agents diffuse into medium well and demonstrated the same activity as discs with antibiotics. For clinical practice it is recommended to use for impregnation the following drugs: gentamycin, meropenem, cefriaxone and ciprofloxacin.

Emergency bleeding presents significant challenges such as high blood flow and rapid hemorrhaging. However, many existing hemostatic bandages face limitations, including the uncontrolled release of hemostatic agents, insufficient mechanical strength, poor adhesion, and complex manufacturing processes. To address these limitations, we developed a multifunctional hydrogel bandage for emergency hemostasis using a one-pot synthesis method.

This study introduces an innovative bio-based sorbent bead crafted by integrating chitosan (CS) biopolymers, Fe(NO3)3 and polydopamine nanoparticles (PDA NPs) via glutaraldehyde crosslinking. The primary focus of this study was the concurrent separation of diverse tetracycline antibiotics (TCs), followed by rigorous reversed-phase liquid chromatography analysis. The fabricated CS/Fe@PDA sorbent beads were comprehensively characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy, revealing a surface rich in active carbon (C), nitrogen (N), and oxygen (O) moieties.
