l-Cysteine functionalized magnetite nanoparticle adorned Ti3C2-MXene nanohybrid based screen printed immunosensor for oral cancer biomarker detection

“…The heterogeneous electron transfer rate constant (K s ) and scan rate are two primary factors responsible for facile electron transfer kinetics. 60 Hence, the Laviron formula was employed for calculating the K s value for the BSA/anti-CYFRA-21-1/L-Cyst@MNPs/Ti 3 C 2 -MXene/GSPE immunosensor, which is 0.187 s −1 , as estimated using eqn (10). Here, m represents the shi in peak potential (V).…”

“…8,9 Biomarkers are molecules whose identication signies a specic diseased condition or a reaction to a therapeutic intervention that can be detected or quantied in blood, serum, plasma, and saliva. 10 Notably, salivary biomarker analysis has surfaced as a promising method for clinical assessment of oral cancer due to its suitability, noninvasiveness, safety, and cost-effectiveness. 11 Recent clinical analysis has demonstrated that CYFRA 21-1 detected in human saliva can be reliable for early diagnosis of oral cancer.…”

Advancement of Metatranscriptomics towards Productive Agriculture and Sustainable Environment: A Review

“…A bioindicator could be from any species or a group of species and other biomaterials or biochemicals that are sensitive to their surrounding environments and can be used to measure the ecosystem’s health. The previous common trend in water ecosystem biomonitoring used higher organisms such as fish [ 85 , 86 ], frogs or toads [ 87 , 88 ], and clams [ 89 , 90 ]. While these approaches are crucial for a deeper comprehension of these populations’ survivability in the affected areas, the routine monitoring and quantification of these species may not be feasible in detecting the specific contamination in a particular area.…”
