Bioinspired nanoarchitectonics opens a new era for designing drug delivery systems.
Supramolecular immobilization of bio-entities for bioelectrochemical applications
Supramolecular systems based on host-guest, electrostatic, or metal-ligand interaction and their use in bioelectrochemical applications are reviewed.
Self-assembly of fatty acids: from foams to protocell vesicles
Stable aqueous dispersions of fatty acids can now be obtained and yield multiple applications.
Compartmentalised chemistry: from studies on the origin of life to engineered biochemical systems
Splitting chemical reactions into microscale compartments is one of the greatest inventions of chemical evolution.
A hybrid lipid oligonucleotide: a versatile tool for supramolecular chemistry
Lipid oligonucleotides (LONs) self-assemble into supramolecular structures. This property has an impact on the biological effects of the oligonucleotide sequences.
Guanosine and isoguanosine derivatives for supramolecular devices
Guanosine (G) and isoguanosine (isoG) derivatives can self-assemble, yielding supramolecules that have found broad applications in diverse fields.
A reversible supramolecular assembly containing ionic interactions and disulfide linkages
A reversible ionic supramolecular assembly is described which can be disrupted and reformed by application of either a heating–cooling cycle or a mild redox reaction.
DNA-controlled aggregation of virus like particles – mimicking a tetherin-like mechanism
Lipophilic DNA with two α-tocopherol anchors, mimicking tetherin, a cell protein reducing spreading of viruses, induces aggregation of virus-like particles.
Diastereoselective self-assembly of clofarabine lipids
Clofarabine lipids form superstructures via diastereoselective self-assembly.
EPR based distance measurement in Cu-porphyrin–DNA
Measurement of EPR spectra of Cu-porphyrin–DNA reveals intermolecular interactions between the DNA strands with average distances of 6.5–8.9 Å.
Cyclodextrin-scaffolded amphiphilic aminoglucoside clusters: self-assembling and gene delivery capabilities
The self-assembling and gene transfer capabilities of monodisperse amphiphilic aminoglucoside–cyclodextrin conjugates depend on the amino disposition at the glycationic head.
A releasable disulfide carbonate linker for polyethyleneimine (PEI)-based gene vectors
In the present research study, we used a releasable disulfide carbonate linker to construct polyethyleneimine-based gene vectors with regulated DNA release.
Efficient synthesis of small-sized phosphonated dendrons: potential organic coatings of iron oxide nanoparticles
Small-sized dendritic phosphonic acids are ideal coatings for iron oxide nanoparticles to be used in vivo.
Nucleolipids as building blocks for the synthesis of 99mTc-labeled nanoparticles functionalized with folic acid
Nucleoside-lipids are efficient bio-inspired amphiphiles for the construction of nanoparticles for image-guided therapy applications.
The impact of two –GlyProGly– motifs on formation of di-copper complexes by His4-cyclopeptides
The interactions of copper(II) ions with the macrocyclic peptide, c(HKHGPG)2, were investigated in aqueous solution as a function of pH by potentiometric titration, spectroscopic (UV-Vis, CD, and EPR) and mass spectrometry (ESI-MS) measurements.
Lipidic spherulites as magnetic resonance imaging contrast agents
Paramagnetic spherulites were successfully obtained following 3 grafting strategies of gadolinium chelate. Grafting onto lipid bilayers gave the best relaxivity results.
About this collection
This themed collection, consisting of 7 review articles and 10 original research papers, covers various types of supramolecular systems at the biological interface: lipids, nucleic acids, peptides, DNA and also various hybrid systems and nanoparticles. Some of the contributions are oriented towards gaining deeper insights into a particular system (self-assembly properties, spectroscopy, intermolecular interactions). Other contributions are focused on applications, particularly in medicine (imaging contrast agents, gene delivery and gene silencing systems, drug delivery).
