Accelerated wound healing and its promoting effects of biomimetic collagen matrices with siderophore loaded gelatin microspheres in tissue engineering.

The prolonged inflammation and elevation of Matrix Metalloproteniases (MMPs) at the wound site causes significant degradation of Extracellular matrix (ECM) which cause delays the process of wound healing. Hence the development of therapeutic dressing matrices to control and to positively regulate MMPs balance was considered important in achieving faster healing. The design of biomaterial matrices of collagen scaffold has the challenge to mimic the function of ECM and emulate to the attraction of fibroblast migration at wound site.

Nanofibrous matrixes with biologically active hydroxybenzophenazine pyrazolone compound for cancer theranostics.

The nanomaterial with the novel biologically active compounds has been actively investigated for application in cancer research. Substantial use of nanofibrous scaffold for cancer research with potentially bioactive compounds through electrospinning has not been fully explored. Here, we describe the series of fabrication of nanofibrous scaffold loaded with novel potential biologically active hydroxybenzo[a]phenazine pyrazol-5(4H)-one derivatives were designed, synthesized by a simple one-pot, two step four component condensation based on Michael type addition reaction of lawsone, benzene-1,2-diamine, aromatic aldehydes and 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one as the substrates.

Design and characterization of 3D hybrid collagen matrixes as a dermal substitute in skin tissue engineering.

The highly interconnected porous dressing material was fabricated with the utilization of novel collagen (COL-SPG) for the efficient healing of the wound. Herein, we report the fabrication of 3D collagen impregnated with bioactive extract (COL-SPG-CPE) to get rid of infection at the wound site. The resultant 3D collagen matrix was characterized physiochemically using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and mechanical property.

Durable keratin-based bilayered electrospun mats for wound closure.

A bilayered nanofibrous scaffold with rapid wound healing properties is found to be suitable for tissue regeneration applications. The objective of this study is to reveal the fabrication of a poly(3-hydroxybutyric acid) (P)-gelatin (G) nanofibrous mat through electrospinning, with a horn keratin-chitosan-based biosheet (KC) as a bilayered nanofibrous scaffold. The mupirocin (D)-loaded horn KC biosheet (KCD) acts as the primary layer over which PG nanofibers were electrospun to act as the secondary layer.
