We have previously reported that tetrazolium salts were both potent and specific inhibitors of Plasmodium replication, and that they appear to interact with a parasite component that is both essential and conserved. The use of tetrazolium salts in vivo is

Methods have been developed for the solid-phase detection of nucleic acids using mixed films of quantum dots (QDs) and oligonucleotide probes in microtiter plates. Polystyrene microwells were functionalized with multidentate imidazole ligands to immobilize QDs. Oligonucleotide hybridization was transduced using

Chemically modified antisense RNA oligonucleotides (antagomir) offer promise for cancer therapies but suffer from poor therapeutic effect after systemic administration. Chemical modification or loading in degradable hydrogels can offer improvements in the accuracy and efficacy for sustained delivery at specific
