NanoSQUIDs are quantum sensors that excel in detecting a small change inmagnetic flux with high sensitivity and high spatial resolution. Here, weemploy resist-free direct-write Ga+ Focused Ion Beam Induced Deposition (FIBID)techniques to grow W-C nanoSQUIDs, and we investigate their electrical responseto changes in the magnetic flux. Remarkably, FIBID allows the fast($3~\mathrm{nm}$) growth of $700~\mathrm{nm}\times 300~\mathrm{nm}$Dayem-bridge nanoSQUIDs based on narrow nanowires ($50~\mathrm{nm}$ wide) thatact as Josephson junctions. The observed transfer coefficient (output voltageto magnetic flux change) is very high (up to $1301~\mathrm{\mu V/\Phi_0}$),which correlates with the high resistivity of W-C in the normal state. Wediscuss here the potential of this approach to reduce the active area of thenanoSQUIDs to gain spatial resolution as well as their integration oncantilevers for scanning-SQUID applications.
