Summary: The thermal performance of a hybrid nanofluid containing graphene oxide (GO)-gold/water and GO/water nanofluid in cooling a CPU was experimentally investigated. The results showed that both the GO/water nanofluid and the GO-gold/water hybrid nanofluid significantly reduced the CPU surface temperature compared with DI water, with reductions of 10.6% and 16.2%, respectively. Furthermore, the convective heat transfer coefficient was improved by 36.36% with the GO-gold/water hybrid nanofluid (0.0094 mass%) and Re = 2185. New correlations for predicting the Nusselt number of the hybrid nanofluids were developed based on experimental data. Overall, the hybrid nanofluid is highly recommended for electronic device cooling.

Summary: This study reports a label-free ultrasensitive electrochemical aptasensor (GO@GNP-A) for detecting cardiac biomarker Troponin I (TnI). The nanohybrid of graphene oxide (GO) and gold nanoparticles (GNP-A) is self-assembled to form the nanohybrid (GO@GNP-A), onto which the biomarker protein is analyzed. TnI interactions at the aptamer biointerfaced nanohybrid surface cause electrochemical signal enhancement. The sensitivity of this nanohybrid aptasensor platform is 0.001 pg/mL. The study has been further validated in clinical samples for early, sensitive, and efficient point-of-care detection of TnI in cases of Acute Myocardial Infarction (AMI).

Summary: A high NIR sensitivity and spectral selectivity photothermal detector was developed by modifying a photothermal layer of reduced graphene oxide-Au nanorods hybrid. The detector converts light energy into heat and measures resistance changes. The hybrid material exhibits remarkable photothermal conversion efficiency and dependence on spectral response, resulting in high sensitivity to illumination in the wavelength range from 700 to 1000 nm.

Summary: In this study, activated platelet targeted gold-iron oxide nanoparticles were developed for the diagnosis and treatment of thrombosis related diseases. The nanoparticles enabled triple imaging modalities of magnetic resonance imaging, photoacoustic imaging, and fluorescence imaging, and also facilitated photothermal thrombolysis. The in vivo observation showed enhanced contrast and thrombus reduction in the targeted group compared to the non-targeted group.

Summary: A multi-effect separation membrane with GO nanosheets was fabricated using L-cysteine functionalized gold nanoparticles as scaffolds and spacers. The membrane showed stability due to the robust spacer provided by the gold nanoparticles. By controlling the pH, the membrane achieved controllable ultrahigh permeance for size sieving. Furthermore, the membrane exhibited high enantioselectivity for chiral separation.

Summary: This study aimed to develop a cost-effective and efficient method for L-cysteine detection by utilizing photochemical preparation of gold nanoparticles and gold nanoparticles on graphene oxide nanostructures. The gold nanoparticles and gold nanoparticles on graphene oxide acted as nano-sensors for detecting L-cysteine due to their interaction with the molecular structure of L-cysteine, resulting in aggregation and color change. Using this method, colorimetric detection of L-cysteine in nanomolar concentrations was successfully demonstrated.
