In this work, we show the realization of a fully-implantable device for monitoring free-moving small animals. The device integrates a microfabricated sensing platform, a coil for power and data transmission and two custom designed integrated circuits. The device is intended to be implanted in mice, free to move in a cage, to monitor the concentration of(More)
Aberrant activation of oncogenes or loss of tumour suppressor genes opposes malignant transformation by triggering a stable arrest in cell growth, which is termed cellular senescence. This process is finely tuned by both cell-autonomous and non-cell-autonomous mechanisms that regulate the entry of tumour cells to senescence. Whether tumour-infiltrating(More)
This paper represents the extended version of the conference paper “Developing highly-integrated subcutaneous biochips for remote monitoring of human metabolism” presented at the IEEE Sensors Conference 2012, and presents data on assembly, packaging and short term in vitro and in vivo biocompatibility evaluation of a fully implantable biosensor array. The(More)
A novel system for remote monitoring of metabolism in an animal model is proposed in this paper. The system is obtained by integrating bio-nano-sensors to detect singlemetabolites, an electrochemical front-end made with off-the-shelf components, a radio frequency communication sub-system, and an antenna of new design. The system has been calibrated and(More)
Laser damage threshold energies produced from ultrashort (i.e., ⩽1 ns) laser pulses are investigated as a function of both pulse width and spot size for an artificial retina. A piece of film acts as the absorbing layer and is positioned at the focus of a variant on the Cain artificial eye [C. Cain, G. D. Noojin, D. X. Hammer, R. J. Thomas, and B. A.(More)
Infiltration of the central nervous system is a severe trait of T cell acute lymphoblastic leukemia. Inhibition of CXC chemokine receptor 4 significantly ameliorates T cell acute lymphoblastic leukemia in murine models of the disease; however, signaling by CXC chemokine receptor 4 is important in limiting the divagation of peripheral blood mononuclear cells(More)
In this work, we showed the realization of a fullyimplantable device that integrates a microfabricated sensing platform, a coil for power and data transmission and integrated circuits. We described a device intended to test the biocompatibility of the materials used for the microfabrication. Therefore, electronics measurements for data communication and(More)
This paper presents the in-vivo tests on a Fully Implantable Multi-Panel Devices for Remote Monitoring of endogenous and exogenous analytes. To investigate issues on biocompatibility, three different covers have been designed, realized and tested in mice for 30 days. ATP and neutrophil concentrations have been measured, at the implant site after the device(More)
