Description:About the seminar:\n\nElectrochemical biosensing platforms offe
 r an affordable alternative to centralized diagnostic screening methods. H
 owever\, current electrochemical detection assays do not offer the same li
 mits of detection as industry standards (i.e. ELISA). In recent years\, La
 ser-Induced Graphene (LIG) electrodes have shown superior electrochemical 
 performance to other commonly used carbon electrodes often employed in suc
 h devices due to their low fabrication cost. This superiority is generally
  attributed to the large electroactive surface area of LIG. Yet\, conventi
 onal electrochemical analytical approaches such as the Randles- Ševčík 
 equation assume diffusion limited mass transport and uniform electrode geo
 metry\, making them incomplete descriptions of the heterogeneous porous re
 gimes present in LIG. This shortcoming in analysis limits our ability to d
 istinguish apparent electroactive surface area from contributions of pore 
 structure\, analyte depletion\, and limited diffusion. Developing more com
 prehensive analytical frameworks is crucial to describe LIG’s structure-
 function relationship and guide its fabrication/integration into biosensin
 g devices. Improved electrochemical characterization may drive performance
  closer to industry-standard detection limits\, enabling the integration o
 f LIG into the development of next-generation scalable electrochemical bio
 sensing assays. 4:00 pm
