Electroceutical Residue-Free Graphene Device for Dopamine Monitoring and Neural Stimulation
The
simultaneous neural signal monitoring and stimulation can allow
accurate neurotransmitter regulation for patients in various degrees
of neural degeneration disorders. Here, we developed a residue-free
graphene device as an effective electrical neural interface for dopamine
sensing and secretion. We demonstrated the ultrasensitive dopamine
sensing of residue-free graphene devices cultured with PC12 cells
and the on-demand functional electrical stimulation for electroceutical
applications. The doping effect of graphene by the released dopamine
from living cells was confirmed from the electrical current change.
The dopamine release could be also quantitatively analyzed by ELISA.
Then, Ca2+ ion-dependent dopamine release was optically
observed by fluorescence microscopy during the stimulation. Taken
together, this study confirms the feasibility of graphene surface
as a neural interface for electroceutical applications to various
central nerve system disorders
Disordered Mixture of Self-Assembled Molecular Functional Groups on Heterointerfaces with p‑Si Leads to Multiple Key Generation in Physical Unclonable Functions
Physical unclonable function (PUF) security devices based
on hardware
are becoming an effective strategy to overcome the dependency of the
internet cloud and software-based hacking vulnerabilities. On the
other hand, existing Si-based artificial security devices have several
issues, including the absence of a method for multiple key generation,
complex and expensive fabrication processes, and easy prediction compared
to devices retaining natural randomness. Herein, to generate unique
and unpredictable multiple security keys, this paper proposes novel
PUF devices consisting of a disordered random mixture of two self-assembled
monolayers (SAMs) formed onto p-type Si. The proposed PUF devices
exhibited multikeys at different voltage biasing, including 0 V, through
the arbitrary dipole effect. As a result, multiple unpredictable hardware
security keys were generated from one device using a simple solution-coating
process. The PUF security device based on the mixture of materials
with different dipoles developed in this study can provide valuable
insights for implementing various PUF devices in the future
