Dataset for "Antimicrobial Releasing Hydrogel Forming Microneedles"

This dataset pertains to a study involving the use of 3D printed microneedles (MNs) to form hydrogel-forming MNs (HFMs) for the delivery of antibiotics (amoxicillin and vancomycin) transdermally. It includes:

- the HFMs ability to swell in fluids over time rapidly and take up drugs in solution as a result (including characterisation of the HFMs and drug loaded-HFMs);
- the mechanical properties and skin penetration of both HFMs and Drug-loaded HFMs;
- the drug release profiles of the drug-loaded HFMs and how to control the release;
- the antimicrobial properties of the antibiotic HFMs against susceptible bacteria.

The data provides a suggestion towards the use of HFMs for the effective transdermal delivery of antibiotics, towards reducing the rate of antimicrobial resistance increase.

Data collection method:

Antimicrobial Properties: Disk Diffusion Assays using E.coli and S.aureus. Samples incuated for 24 hours. Optically monitored the area of inhibition surrounding the HFMs. Data provided are images, analysed using ImageJ with data saved in text file. Drug Release: Drug loaded HFMs were submerged in PBS. PBS samples were taken over time and UV-Vis analysis was used to calculate the concentration of drug that has been release. Data is in the form of Excel document. Mechanical properties: HFMs were tested on a DMA up to 10 newtons. Data is proved in the form of Excel document. Skin Penetration: HFMs were placed on porcine skin and a known force was applied and the resultant skin pores were optically imaged. Data is in the form of images. Swelling: HFMs were submerged in PBS. The mass of the HFMs was taken at various time points. The data provided is in the form of an Excel file. Raw data and data analysis can been found in the respective files.

Technical details and requirements:

The data is provided in MS Excel format.
