Macroporous resins are generally highly (>5%, typically 20-25%) crosslinked polystyrene microbeads [9,10,21]. The term macroporous refers to their inner skeleton, which is made of a permanent porous structure even in the dry state (cf Scheme Ic). Historically, functionalised macroporous resins have mainly been used for ion exchange and separation. Nowadays, many new applications, especially in the field of polymer-supported reagents [31, 32] and catalysts [5,7], have been developed. 

Due to the easy handhng of polystyrene microbeads a large number of recent reviews have appeared to highhght the tremendous developments in this area [3-8]. Some more detailed examples are presented in the chapter of Uozumi et al. Despite the great efforts made in this area, it should be noted that many catalytic reactions using transition metal catalysts in combination with sohd phase supports often require larger amoimts (1-100 mol%) of catalyst due to... 

In our study, a carboxylated polystyrene microbead (Polybead Carboxyl-ate Microsphere, r = 5 /um, Polyscience, Inc., Warrington, PA) was used.

CdSci.xTCx QDs were synthesised by the rapid injection of TOPSe and TOPTe precursors to CdO dispersed in oleic add-paraffin liquid mixture at 200-260 TEM analysis revealed the formation of spherical particles of ca. 5 nm size with cubic zinc blende phase. They exhibit high PL quantum yield (20-70%) with broad emission ranging from 600 30 nm. These NIR QDs were incorporated in carboxyl capped porous polystyrene microbeads and successfully used for bio-labelKng.
