Structural electronics, as well flexible and wearable devices are applications that possible by merging polymers with metal nanoparticles. However, using conventional technologies, it is challenging to fabricate plasmonic structures remain flexible. We developed three-dimensional (3D) nanostructures/polymer sensors via single-step laser processing further functionalization 4-nitrobenzenethiol (4-NBT) a molecular probe. These allow ultrasensitive detection surface-enhanced Raman spectroscopy...
Graphene oxide (GO) possesses specific properties that are revolutionizing materials science, with applications extending from flexible electronics to advanced nanotechnology. A key method for harnessing GO's potential is its laser-induced reduction, yet the exact mechanisms - photothermal versus photochemical effects remain unclear. Herein, we discover dominant role of reactions in laser reduction GO under visible light, challenging prevailing assumption dominant. Employing a combination...
Flexible electronics have sparked significant interest in the development of electrically conductive polymer-based composite materials. While efforts are being made to fabricate these composites through laser integration techniques, a versatile methodology applicable broad range thermoplastic polymers remains elusive. Moreover, underlying mechanisms driving formation such not thoroughly understood. Addressing this knowledge gap, our research focuses on core processes determining reduced...
Since discovering two-dimensional materials, there has been a great interest in exploring, understanding, and taking advantage of their unique properties. Si/SiO2 is one the most used substrates for deposition characterization 2D materials due to its availability optical contrast. This work goes beyond conventional substrate introduces highly-ordered pyrolytic graphite (HOPG) as universal support investigating several properties such chemical temperature stability, intrinsic high flatness,...
We report the high-powered laser modification of chemical, physical, and structural properties two-dimensional (2D) van der Waals material GaSe. Our results show that contrary to expectations previous reports, GaSe at periphery a high-power beam does not entirely decompose into Se Ga2O3. In contrast, we find unexpectedly Raman signal from gets amplified around regions where it was expected exist. Atomic force microscopy (AFM), dielectric (DFM), scanning electron (SEM), energy-dispersive...
