Development Of Rice Starch Microneedles For Drug Delivery To The Skin

Microneedles (MNs) are minimally invasive biomedical devices that help drugs to bypass the skin barrier, resulting in systemic and localised pharmacological effects. Dissolving MNs are associated with high patient compliance and lower cross-contamination risk as compared to other MN types. Rice star...

Development Of Rice Starch Microneedles For Drug Delivery To The Skin
description Microneedles (MNs) are minimally invasive biomedical devices that help drugs to bypass the skin barrier, resulting in systemic and localised pharmacological effects. Dissolving MNs are associated with high patient compliance and lower cross-contamination risk as compared to other MN types. Rice starch (RSC) has a high potential to be used in the development of dissolving MNs owing to its good film-forming properties, biodegradability, non-toxicity, and low cost. However, formulation of dissolving MNs using RSC is challenging due to the inherent brittleness of RSC. This thesis aims to explore RSC as a biopolymer for the fabrication of dissolving MN for drug delivery to the skin.
