DNA origami plasmonics
DNA origami plasmonics is the use of scaffolded DNA origami structures as nanoscale templates to arrange metallic nanoparticles into precise configurations, enabling engineered optical responses.
DNA origami rotary motor
A DNA origami rotary motor is a nanoscale rotating machine self-assembled from DNA strands that imitates biological motors like ATP synthase, driven by electric fields, ion gradients, or strand displacement.
DNA supercoil
DNA supercoiling is the coiled state of double-stranded DNA whose ends are topologically constrained, where the helix is overwound or underwound, affecting transcription, replication, and chromosome segregation.
DNA tetrahedron
A DNA tetrahedron, or tetrahedral DNA nanostructure, is a pyramid-shaped nanostructure self-assembled from four DNA strands, first reported in 2004 and widely used in biosensing and drug delivery.
DNA-assembled chiral plasmonic oligomers
DNA-assembled chiral plasmonic oligomers are nanoscale clusters of gold or silver nanoparticles arranged by a DNA template into a chiral geometry, giving strong circular dichroism in the visible range.
DNA-based molecular tension sensors
DNA-based molecular tension sensors are nucleic acid probes that convert the mechanical unfolding or rupture of a DNA element into fluorescence, reporting piconewton receptor forces.
DNA-crosslinked hydrogel
A DNA-crosslinked hydrogel, commonly called a DNA hydrogel, is a 3D polymer network in which DNA strands act as the framework or cross-links, making stiffness and response programmable through sequence design.
DNA-mediated colloidal assembly
DNA-mediated colloidal assembly is a self-assembly strategy in which colloidal particles grafted with single-stranded DNA form sequence-specific, thermoreversible bonds, organizing into prescribed crystals, gels, and finite structures.
DNA-mediated colloidal crystallization
DNA-guided colloidal crystallization is a self-assembly strategy in which particles coated with synthetic DNA act as programmable atoms, crystallizing into lattices with independently controlled symmetry, spacing, and composition.
DNA-modified electrode
A DNA-modified electrode is an electrochemical electrode whose surface carries immobilized DNA probes, so hybridization with a matching target sequence produces a measurable electrical signal for diagnostics.
DNA-origami-based chiral plasmonics
DNA-origami-based chiral plasmonics is a nanofabrication approach using DNA origami scaffolds to arrange gold nanoparticles into chiral helices, first demonstrated in 2012 and applied to biosensing.
DNA-programmable assembly of nanocrystal superlattices
DNA-programmable assembly of nanocrystal superlattices is a nanofabrication method in which DNA-coated nanoparticles self-assemble, through complementary base pairing, into crystals with designed symmetry and spacing.
DNA-programmed colloidal assembly
DNA-programmed colloidal assembly is a materials-synthesis method in which colloidal particles coated with DNA strands bind selectively and self-assemble into prescribed crystals, first shown with gold nanoparticles in 1996.
DNA-templated silver nanoclusters
DNA-templated silver nanoclusters (DNA-AgNCs) are fluorescent clusters of a few dozen silver atoms stabilized by DNA, first made in 2004 and used for biosensing and bioimaging.
DNA-templated synthesis
DNA-templated synthesis is a method of performing chemical reactions in which DNA base pairing brings reagents together, controlling which reaction occurs and encoding each product's identity; it was first described by Gartner and Liu in 2001.
DNAPL
DNAPL (dense non-aqueous phase liquid) is an organic liquid denser than water and only slightly soluble in it; common examples include TCE, PCE, coal tar, and PCB-containing oils.
DNTT
Dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT) is a p-type organic semiconductor synthesized in 2007 by Yamamoto and Takimiya at Hiroshima University, known for air stability and use in flexible and implantable OFET electronics.
DØ experiment
The DØ experiment, also written DZero, was a general-purpose particle detector at Fermilab's Tevatron collider that, together with CDF, discovered the top quark in 1995 and operated until 2011.
Do-calculus
Do-calculus is a system of three inference rules, introduced by Judea Pearl in 1995, that determines whether causal effects can be computed from non-experimental, observational data alone.
Docking (molecular)
Molecular docking, also called ligand docking, is a computational method that predicts the binding pose of a ligand in a protein site and estimates affinity.
Docosanol
Docosanol, also known as behenyl alcohol, is a saturated 22-carbon fatty alcohol and the active ingredient in 10% cream that shortens the healing time of cold sores.
Docosapentaenoic acid
Docosapentaenoic acid (DPA) is an omega-3 fatty acid with 22 carbons and five double bonds, found in fish oil and human milk, and an intermediate between EPA and DHA.
Documentary analysis
Documentary analysis is a qualitative social-science method of systematically examining and interpreting existing documents, whose defining feature is that the data already exist before the research begins.
Dodecagon
A dodecagon is a polygon with 12 sides and 12 vertices; in the regular case each interior angle measures 150° and the shape has 12 lines of symmetry.
Dodecagonal quasicrystal in block copolymers
A dodecagonal quasicrystal in block copolymers is a soft-matter phase in which spherical micelles form a quasiperiodic tiling with 12-fold symmetry, first seen in polymers in 2007.
Dodecahedron
A dodecahedron is any polyhedron with twelve faces, and in everyday use usually means the regular dodecahedron, a Platonic solid of twelve pentagonal faces, 30 edges, and 20 vertices.
Dodecan 1 ol
Dodecan-1-ol (1-dodecanol, lauryl alcohol, dodecyl alcohol), C12H26O, CAS 112-53-8, is a saturated C12 fatty alcohol used as a surfactant intermediate, EU-approved moth mating-disruption pheromone, and feed flavoring additive.
Dodecane
Dodecane, also called n-dodecane, is the straight-chain alkane with the formula C₁₂H₂₆, a colorless combustible liquid that boils at about 216 °C and is a component of gasoline.
Dodecyl acetate
Dodecyl acetate (lauryl acetate, acetate C-12, CAS 112-66-3) is the C12 fatty alcohol acetate ester, C14H28O2, a waxy citrus-rose odor liquid used as a flavoring agent, fragrance ingredient, and EU-approved low-risk insect attractant pheromone.
