Effects of Poloxamers as Excipients on Electrospun Polycaprolactone (PCL) Fibres′ Physicomechanical Properties, Cellular Biocompatibility and In Vitro Drug Release

Erina Sihih

Electrospinning is a versatile technique used to fabricate nanofibrous structures with a wide range of applications, including tissue engineering and drug delivery systems. Polycaprolactone (PCL) is a commonly used polymer in electrospinning due to its biocompatibility, biodegradability, and mechanical properties. However, PCL alone may not possess the desired properties for certain applications. To enhance the functionality of PCL fibres, the addition of excipients such as poloxamers has been explored. Poloxamers are triblock copolymers that exhibit unique physicochemical properties, including thermosensitivity, surfactant properties, and biocompatibility. This article aims to explore the effects of poloxamers as excipients on the physicomechanical properties, cellular biocompatibility, and in vitro drug release of electrospun PCL fibres.

Iron Chelation and Total Bio−Based Materials for Drug Delivery in the Battle against Cancer

Pio Zagni

Cancer is one of the leading causes of death worldwide, with millions of people affected by this devastating disease each year. While significant progress has been made in the field of cancer treatment, there is still a pressing need for more effective and targeted therapeutic strategies. In recent years, iron chelation and total bio-based materials have emerged as promising approaches for drug delivery in the battle against cancer. This article will explore the potential of these innovative techniques and their impact on improving cancer treatment outcomes. Iron is an essential element for normal cellular function, but it can also play a role in cancer progression. Tumor cells often have an increased demand for iron to support their rapid growth and proliferation. Therefore, targeting iron metabolism in cancer cells has become an attractive strategy for therapeutic intervention. Iron chelation refers to the process of binding and removing excess iron from the body. By reducing the availability of iron, chelation therapy can hinder tumor growth and enhance the effectiveness of traditional cancer treatments.
