Selective room temperature phosphorescence detection of heparin based on manganese-doped zinc sulfide quantum dots/polybrene self-assembled nanosensor

Simultaneous estimation of vitamin K1 and heparin with low limit of detection using cascaded channels fiber optic surface plasmon resonance

“…However, these should be present in some specific ratio otherwise MWCNTs can have some adverse effects like pathogenicity activity (Poland et al, 2008). Polybrene has been used for the sensing of heparin (Liu et al, 2015;Zhang et al, 2015) because polybrene neutralizes heparin involving chemical reactions/interactions (Montalescot et al, 1990;Tientadakul et al, 2013). In the proposed sensor for heparin sensing, ZnO has been introduced in the form of shell with polybrene as a central core because it has been recently reported by us that ZnO along with the sensing material increases the evanescent field and consequently the sensing performance of the SPR based sensor (Tabassum and Gupta, 2015).…”

Preparation of DNA functional phosphorescent quantum dots and application in melamine detection in milk

“…As PQDs [16][17][18] not only have advantages such as long uorescence lifetime, high selectivity, broad linearity range, high sensitivity and good repeatability but also can avoid disturbance from background uorescence and scattered light of the biological uid, 19,20 especially Mn-ZnS QDs, which have superior optical properties, have been widely applied in the biomolecular detection process. 21,22 If DNA-PQDs are prepared using DNA as the template, this will greatly widen the application range of existing Mn-ZnS PQDs in biology.…”

“Turn on” room-temperature phosphorescent biosensors for detection of hyaluronic acid based on manganese-doped ZnS quantum dots

“…[33][34][35][36] Recently, room-temperature phosphorescence (RTP) QDs detection has attracted much attention. [37][38][39][40][41] Compared with uorescence QDs, phosphorescent QDs survive longer, better avoid the interference from scattering and autouorescence, and do not need complex sample pretreatment. 37,39,42 Moreover, phosphorescence is rarer than uorescence and thus is more efficient and selective in practice.…”
