    • openAccess   Chemically Fueled Autonomous Sol→Gel→Sol→Gel→Sol Transitions 

      Hermans, Thomas; Singh, Nishant Wiley (2023-06-05)
      Complex non-equilibrium phase behaviors are a hallmark of natural self-assembling systems. Here we show how intricate phase transitions can be achieved through a chemically fueled reaction cycle to yield autonomous ...

    • openAccess   Chemically Fueled Self-Sorted Hydrogels 

      Singh, Nishant; Lopez-Acosta, Alvaro; Formon, Georges Jacques Marie; Hermans, Thomas American Chemical Society (2022-01-12)
      Narcissistic self-sorting in supramolecular assemblies can help to construct materials with more complex hierarchies. Whereas controlled changes in pH or temperature have been used to this extent for two-component self-sorted ...

    • closedAccess   Competition versus Cooperation in Catalytic Hydrogelators for anti-Selective Mannich Reaction 

      Singh, Nishant; Escuder, Beatriu Wiley (2017-07-21)
      Chemical systems find similarities in different sociological and biological processes, in which the entities compete or cooperate for a favorable outcome. The structural and functional adaptations leading to emergent ...

    • openAccess   Insight into the esterase like activity demonstrated by an imidazole appended self-assembling hydrogelator 

      Singh, Nishant; Conte, M. P.; Ulijn, R. V.; Miravet, Juan; Escuder, Beatriu Royal Society of Chemistry (2016)
      A low molecular weight hydrogelator with a covalently appended imidazole moiety is reported. Capable of percolating water in the pH range of 6 to 8, it proves to be an efficient catalyst upon self-assembly, showing ...

    • closedAccess   Peptide-Based Molecular Hydrogels as Supramolecular Protein Mimics 

      Singh, Nishant; Kumar, Mohit; Miravet, Juan; Escuder, Beatriu Wiley (2017-01-23)
      This Minireview concerns recent advances in the design, synthesis, and application of low molecular-weight peptidic hydrogelators. The sequence-specific combinations of amino acid side chain functionalities combined with ...

    • openAccess   Re-programming Hydrogel Properties Using a Fuel-Driven Reaction Cycle 

      Singh, Nishant; Lainer, Bruno; Formon, Georges Jacques Marie; De Piccoli, Serena; Hermans, Thomas American Chemical Society (2020-03-04)
      Nature uses catalysis as an indispensable tool to control assembly and reaction cycles in vital non-equilibrium supramolecular processes. For instance, enzymatic methionine oxidation regulates actin (dis-)assembly, and ...

    • closedAccess   Synthesis of a Double-Network Supramolecular Hydrogel by Having One Network Catalyse the Formation of the Second 

      Singh, Nishant; Maity, Chandan; Zhang, Kai; Angulo-Pachón, César A.; van Esch, Jan; Eelkema, Rienk; Escuder, Beatriu Wiley (2017-02-10)
      elf-assembly of biomolecules catalytically controls the formation of natural supramolecular structures, giving highly ordered complex materials. Such desirable hybrid systems are very difficult to design and construct ...

    • openAccess   Tandem reactions in self-sorted catalytic molecular hydrogels 

      Singh, Nishant; Zhang, Kai; Angulo-Pachón, César A.; Mendes, Eduardo; van Esch, Jan; Escuder, Beatriu Royal Society of Chemistry (2016)
      By equipping mutually incompatible carboxylic acid and proline catalytic groups with different self-assembling motives we have achieved self-sorting of the resulting catalytic gelators, namely SucVal8 and ProValDoc, into ...

    • closedAccess   Towards Supramolecular Catalysis with Small Self-assembled Peptides 

      Singh, Nishant; Tena Solsona, Marta; Miravet, Juan; Escuder, Beatriu Wiley-VCH Verlag (2015-04)
      Self-assembly of small peptides offers unique opportunities for the bottom-up construction of supramolecular catalysts that aim to emulate the efficiency and selectivity of natural enzymes. Small, information-rich, simple ...
