RESUMO
INTRODUCTION: Chronic wounds require more sophisticated care than standard wound care because they are becoming more severe as a result of diseases like diabetes. By resolving shortcomings in existing methods, 3D-bioprinting offers a viable path toward personalized, mechanically strong, and cell-stimulating wound dressings. AREAS COVERED: This review highlights the drawbacks of traditional approaches while navigating the difficulties of managing chronic wounds. The conversation revolves around employing natural biomaterials for customized dressings, with a particular emphasis on 3D-bioprinting. A thorough understanding of the uses of 3D-printed dressings in a range of chronic wound scenarios is provided by insights into recent research and patents. EXPERT OPINION: The expert view recognizes wounds as a historical human ailment and emphasizes the growing difficulties and expenses related to wound treatment. The expert acknowledges that 3D printing is revolutionary, but also points out that it is still in its infancy and has the potential to enhance mass production rather than replace it. The review highlights the benefits of 3D printing for wound dressings by providing instances of smart materials that improve treatment results by stimulating angiogenesis, reducing pain, and targeting particular enzymes. The expert advises taking action to convert the technology's prospective advantages into real benefits for patients, even in the face of resistance to change in the healthcare industry. It is believed that the increasing evidence from in-vivo studies is promising and represents a positive change in the treatment of chronic wounds toward sophisticated 3D-printed dressings.
RESUMO
Polymeric micelles have opened up new horizons for improving drug delivery to brain particularly due to their small size, long circulation time, good stability and targetability. They are used to treat a variety of brain conditions, including glioblastoma, migraine, Alzheimer's, Parkinson's, and other conditions linked to the brain. Micelles are currently underutilised in brain targeting despite having several benefits and spanning a wide variety of brain illnesses. Since most medications are unable to cross the blood brain barrier, scientists are continuously working to discover efficient solutions to the problems. The most pressing issue was thought to be the viability and difficulties of translating micelles into the therapeutic setting. This review describes the role of micellar delivery system in brain diseases treatment along with their route of administration and outcomes. The review also discusses the current state of patents and clinical trials in the relevant fields and their potential future applications.
