Figure Lengend Snippet: ( a ) Microphotograph of the NMR single‐chip detector, fabricated using a 130 nm CMOS technology from STMicroelectronics. The integrated planar microcoil is realized using four copper metal layers. The total number of turns is 22 and the outer diameter is 150 μm (see inset). The details of the microcoil and of the co-integrated electronics are reported in Ref. (33). ( b ) Sensitivity maps of the microcoil (the sensitivity is defined as B uxy ( r )sin( ϑ ), see main text). The microcoil lies in the yz plane and the static magnetic field B 0 lies along the z axis. The sensitivity in the xz (top) and xy (bottom) planes are computed for a pulse length τ = 3.7 μs and an excitation current I = 9 mA. Dark red color identifies the region of maximum sensitivity. ( c ) Rendered image of the single chip integrated detector combined with the 3D printed microfluidic structure. ( d ) Illustration of the approach used to place the sample onto the most sensitive area of the excitation/detection microcoil. The flow drives the sample in proximity of the integrated microcoil. The dashed arrow indicates the direction of insertion of the ovum, which is trapped by two 10-μm-high pillars. A 50-μm-high pillar is employed to block the sample in case of accidental overpressure. A 10‐μm‐thick crosslinked IP-S photoresist layer defines the spacing between the sample and the chip surface (see inset).

Figure Lengend Snippet: ( a ) Schematic of the microchannel used to trap a single Rc ovum. A close up view of the trapping pillars is shown. Two 10-μm-high pillars trap the ovum, while a second pillar is implemented to prevent the loss of the ovum in case of accidental overpressure. ( b ) Top view optical microscope picture of the central part of the microchannel. ( c ) SEM picture of a microchannel section appropriately 3D printed to better visualize the trapping system. ( d ) Schematic of the microchannel used to trap a single C . elegans worm. Close up views of the trapping pillars and the central part of the microfluidic structure are shown in the insets. ( e ) Top view optical microscope picture of the pillars used to trap the head or tail of the C . elegans . ( f ) Top view optical microscope picture of the three microfluidic channels. The central microchannel traps the worm while the two lateral ones provide food to the trapped C . elegans . ( g ) SEM picture of a 3D printed channel section showing the trapping pillars. ( h ) SEM picture of a 3D printed channel section showing the central trapping microchannel and two lateral feeding microchannels.
