<P>Highly fluorescent tetrazine-modified TiO2 nanoparticles were prepared by the reaction of triethoxysilane-appended chloroalkoxy tetrazine (ESTZ) with TiO2 nanoparticles through a condensation reaction between the surface hydroxyl groups of an electrode and the silane anchor group of ESTZ. The prepared electrodes were used as robust fluorescent layers for electrochemical fluorescence switching (electrofluorochromism) applications in the presence of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) as a charge balancing mediator. The stable charge balancing mediator, TEMPO, in the electrolyte was found to be essential to reduce the intrinsic electron transport resistance of TiO2 in order to achieve reversible electrofluorescence switching. Furthermore it facilitated a fully reversible electrochemical reaction and provided a sufficient charge balance, which allowed us to realize semiconductor-based electrofluorescence switching with an on/off ratio of 4.0 and cyclability greater than 100 cycles.</P>

Adequate positioning of the hand is a critical step in hand fracture operative repair that can impact both the clinical outcome and the efficiency of the operation. In this paper, we introduce the use of a thermoplastic splint with an added thumb stabilizing component as a means to increase the surgeon's autonomy and to streamline the patient care pathway. The thermoplastic splint is custom fabricated preoperatively by the specialist hand therapist. The splint is used prior, during, and post operation with minimal modification. The thumb component assists maintaining the forearm in a stable pronated position whilst drilling and affixing metal work. This is demonstrated in the video of removal of metal work and open reduction and internal fixation of a metacarpal fracture.
