Dendrimer-mediated permeation enhancement of chlorhexidine digluconate: Determination of in vitro skin permeability and visualisation of dermal distribution (2021)
Journal Article

Chlorhexidine digluconate (CHG) is a cationic bisbiguanide used in the UK as the first-line skin antiseptic prior to surgery in the UK due to its favourable efficacy and safety profile, high affinity for skin binding and minimal reports of resistance...

Development of a Gaussian Process - feature selection model to characterise (poly)dimethylsiloxane (Silastic (R)) membrane permeation (2020)
Journal Article

Objectives The current study aims to determine the effect of physicochemical descriptor selection on models of polydimethylsiloxane permeation. Methods A total of 2942 descriptors were calculated for a data set of 77 chemicals. Data were processed to...

Model fitting for small skin permeability data sets: hyperparameter optimisation in Gaussian Process Regression (2018)
Journal Article

Objectives The aim of this study was to investigate how to improve predictions from Gaussian Process models by optimising the model hyperparameters. Methods Optimisation methods, including Grid Search, Conjugate Gradient, Random Search, Evoluti...

Dendrimer pre-treatment enhances the skin permeation of chlorhexidine digluconate: Characterisation by in vitro percutaneous absorption studies and Time-of-Flight Secondary Ion Mass Spectrometry (2017)
Journal Article

Abstract Skin penetration and localisation of chlorhexidine digluconate (CHG) within the skin have been investigated in order to better understand and optimise the delivery using a nano polymeric delivery system of this topically-applied antimicrobia...

Introduction (2015)
Book Chapter

This chapter describes the physiology and structure of the skin, emphasising and focusing on the skin's main barrier to permeation – the stratum corneum – and how its structure and nature, compared to other regions and layers of the skin, results in... Read More about Introduction.

The application of machine learning to the modelling of percutaneous absorption: An overview and guide (2015)
Journal Article

Machine learning (ML) methods have been applied to the analysis of a range of biological systems. This paper reviews the application of these methods to the problem domain of skin permeability and addresses critically some of the key issues. Specific...

Distribution and Visualisation of Chlorhexidine Within the Skin Using ToF-SIMS: A Potential Platform for the Design of More Efficacious Skin Antiseptic Formulations (2013)
Journal Article

Purpose In order to increase the efficacy of a topically applied antimicrobial compound the permeation profile, localisation and mechanism of action within the skin must first be investigated. Methods Time-of-flight secondary ion mass spectromet...

Optical Coherence Tomography to delineate the interactions of PAMAM dendrimers with the porcine skin surface (2013)
Journal Article

Polyamidoamine (PAMAM) dendrimers have been topically applied to the skin and utilised as a permeation enhancer for a range of therapeutic compounds. However, very little is known about the mechanism of enhancement. This study used optical coherence...
