【Abstract】 Aptamers are a new class of synthetic DNA/RNA oligonu cleo tides generated from in vitro selection to bind with various molecules. Due to t heir high affinity and specificity, aptamers are becoming promising reagents in protein detection and analysis, disease treatment and new drug selection, biose nsor and molecular switch development, etc. Advances in the study and applicatio ns of aptamers are reviewed.更多还原
