Surface-immobilized peptide aptamers as probe molecules for protein detection.
Steven Johnson,David Evans,Sophie Laurenson,Debjani Paul,A. Giles Davies,Paul Ko Ferrigno,Christoph Wälti +6 more
TL;DR: A strong relationship between binding affinity and aptamer orientation is demonstrated and the affinity constant KD is determined for the interaction between an oriented peptide aptamer ST(cys+)_(pep9) and the target protein CDK2.

The electrophotonic silicon biosensor
José Juan-Colás,Alison Parkin,Katherine E. Dunn,Mark G. Scullion,Thomas F. Krauss,Steven Johnson +5 more
TL;DR: An electrochemical silicon photonic sensor capable of highly sensitive and multiparameter profiling of biomarkers, exploiting both the photonic and the electrical properties of silicon, which opens new modalities for sensing on the microscale.
Common-path interferometric label-free protein sensing with resonant dielectric nanostructures
TL;DR: A common-path interferometric sensor based on guided-mode resonances to combine high performance with inherent stability and indicates the utility for an exemplary application in antibiotic guidance, and opens possibilities for detecting further clinically or environmentally relevant small molecules with an intrinsically simple and robust sensing modality.
Bilateral versus unilateral cochlear implantation in young children
M. Tait,T.P. Nikolopoulos,L. De Raeve,Steven Johnson,G. Datta,Eva Karltorp,E. Ostlund,U. Johansson,E. van Knegsel,Emmanuel A. M. Mylanus,P.M.H. Gulpen,M. Beers,Johan H. M. Frijns +12 more
TL;DR: Profoundly deaf bilaterally implanted children are significantly more likely to use vocalisation to communicate, and to use audition when interacting vocally with an adult, compared with unilaterally implanted children.

Guided mode resonance sensor for the parallel detection of multiple protein biomarkers in human urine with high sensitivity.
TL;DR: The combined sensing and imaging capability of a guided mode resonance (GMR) sensor is used to detect multiple biomarkers (troponin, procalcitonin and C-Reactive Protein) in parallel in undiluted urine samples to relieve the pressure on overstretched healthcare services.
