Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Fluorescent Nanosensor for Indole‐3‐Propionic Acid Detection in Gut Health Monitoring

open access: yesAdvanced Healthcare Materials, EarlyView.
This work introduces a fluorescent nanosensor system with two optical modalities for detection of indole‐3‐propionic acid (IPA) gut metabolite: (1) blue‐emitting cationic conjugated polyelectrolyte (CP3) and (2) near‐infrared (NIR)‐emitting CP3‐wrapped single‐walled carbon nanotube (SWNT).

Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]

open access: yes, 2008
The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.
