Physical Adsorption‐Driven Assembly of Au‐Locked Nucleic Acid (LNA) Probes on MoS2 Nanosheets for SERS‐Based Detection of microRNAs (miRNAs)

open access: yesAdvanced Materials Interfaces, EarlyView.
The Au‐LNA Raman probe, composed of gold nanoparticles (AuNPs), thiol functional group, and Cy3 modified LNAs, synthesized after hybridization of LNA and miR‐210‐3p target, is integrated into the MoS2@Au composite. The integration of the nanocomposite is formed by physical adsorption of Au‐LNA nanohybrid with MoS2. Characterization confirms morphology,

Biomechanical Performance of Additively Manufactured Bone‐Mimicking Scaffolds with Graded Architectures

open access: yesAdvanced Materials Technologies, EarlyView.
Nozzle temperature of 180 °C suits well for supportless PLA stochastic scaffolds. The scaffolds exhibit higher strength and stiffness under sudden impact loading. Grading type shows significant influence on scaffold properties. Radial descending type performs best in both mechanical and permeability aspects. Graded stochastic scaffolds are suitable for
