A Natural deep eutectic solvent as an effective material for dual debridement and antibiofilm effects in chronic wound treatment.

In chronic wound treatment, the debridement of devitalized tissue and the eradication of the biofilm must balance aggressiveness with care to protect regenerating tissues. In this study, urea, a potent chaotropic molecule, was modulated through the formation of a Natural Deep Eutectic Solvent (NADES) with betaine to develop a new debriding material (BU) suitable for application into injured dermal tissues. To evaluate BU's debriding capacity, along with its antibiofilm effect and biocompatibility, pre-clinical to clinical methods were employed.

Ultrastructural characterisation of young and aged dental enamel by atomic force microscopy.

Recent advances in atomic force microscopy (AFM) have allowed the characterisation of dental-associated biomaterials and biological surfaces with high resolution. In this context, the topography of dental enamel - the hardest mineralised tissue in the body - has been explored with AFM-based approaches at the microscale. With age, teeth are known to suffer changes that can impact their structural stability and function; however, changes in enamel structure because of ageing have not yet been explored with nanoscale resolution.

A therapeutic shock propels Schwann cells to proliferate in peripheral nerve injury.

Damage to the peripheral nervous system (PNS) is a prevalent issue and represents a great burden to patients. Although the PNS has a good capacity for regeneration, regeneration over long distances poses several difficulties. Several recent studies have addressed Schwann cells' limited proliferative capacity; however, a solution has yet to be found.
