Arm Intervention/treatment
Experimental: Healthy volunteer Drug: Phenoxymethyl Penicillin
Phenoxymethylpenicillin tablets, 500mg every six hours for six doses, starting the day before study

Device: Microneedle array
The microneedle biosensor will be sited peripherally (on the non-dominant arm) for the duration of the study. It will then be removed.

Primary Outcome Measures :
  1. Assessment of the biosensors ability to track phenoxymethylpenicillin concentrations compared to observations made by microdialysis and blood sampling [ Time Frame: Up to 12 hours ]
    Bland-Altman plot to describe agreement between interstitial phenoxymethylpenicillin concentrations and microneedle data
