A responsive pure DNA hydrogel for label-free detection of lead ion

Emerging low-molecular weight nucleopeptide-based hydrogels: state of the art, applications, challenges and perspectives

“…[68][69][70] While long DNA strands have also been reported to form hydrogels, they suffer, inter alia, from their high cost. 39,40,71,72 Thus, low-molecular weight gelators incorporating nucleobases have been favoured and several molecular structures have been reported, 19,39,41 such as derivatized nucleosides, sugar and lipids, or via the synthesis of bolaamphiphile compounds (see (2)-( 4) Fig. 2B for some examples) or, more recently, via the functionalization of peptide sequences.…”

Novel Aminosilane (APTES)-Grafted Polyaniline@Graphene Oxide (PANI-GO) Nanocomposite for Electrochemical Sensor

“…Other sources include lead battery manufacturers, lead-based pigment manufacturers, automobile industries, decayed water-carrying metal pipes and contaminated consumer products [ 20 ]. Exposure to lead at a certain concentration has been implicated with several health problems such as renal dysfunction, nervous system impairment, headache, fatigue, constipation and brain development impairment in children [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ].…”

Designer DNA biomolecules as a defined biomaterial for 3D bioprinting applications

“…131 Hydrogels based on DNA could be made using pristine DNA or DNA as a chief source material to control the gelation behavior of the hybrid DNA gels. 206,207 Interestingly, the macroscopical hydrogel behavior of DNA can be tuned by rationally controlling the responsive nature of DNA, nanoscale internal architecture, and also other functional motifs of the DNA sequences. 46,208 Taking advantage of these unique features, research has been conducted on various applications of DNA hydrogels such as tissue engineering, cell targeting, drug delivery, and immunotherapy.…”
