Abstract
BACKGROUND The construction of gels from low molecular weight gelators (LMWG) has been extensively studied in the fields of bio-nanotechnology and other fields. However, the understanding gaps still prevent the prediction of LMWG from the full design of those gel systems. Gels with multicomponent become even more complicated because of the multiple interference effects coexist in the composite gel systems. AIM OF REVIEW This review emphasizes systems view on the understanding of multicomponent low molecular weight gels (MLMWGs), and summarizes recent progress on the construction of desired networks of MLMWGs, including self-sorting and co-assembly, as well as the challenges and approaches to understanding MLMWGs, with the hope that the opportunities from natural products and peptides can speed up the understanding process and close the gaps between the design and prediction of structures. KEY SCIENTIFIC CONCEPTS OF REVIEW This review is focused on three key concepts. Firstly, understanding the complicated multicomponent gels systems requires a systems perspective on MLMWGs. Secondly, several protocols can be applied to control self-sorting and co-assembly behaviors in those multicomponent gels system, including the certain complementary structures, chirality inducing and dynamic control. Thirdly, the discussion is anchored in challenges and strategies of understanding MLMWGs, and some examples are provided for the understanding of multicomponent gels constructed from small natural products and subtle designed short peptides.

Abstract
Degradable mesoporous organosilica nanoparticles (MONPs) are attracting significant attention in the area of designing smart drug carriers mainly due to their excellent stability and multiple functions. However, the efficient, controllable, and large-scale production of MONPs still faces huge challenges. Herein, a novel and facile continuous-flow nanoprecipitation strategy was reported to synthesize hollow MONPs with highly uniform and tailored properties. The synthesized hollow MONPs possessed a large surface area (SBET > 1070.1 m2 g-1), narrow size distribution, large hollow cavity, and thin shell. Interestingly, the incorporation of organic moieties into silica cross-linked networks led to the timely degradation of nanocarriers with the desired responsiveness. Moreover, the applicability of the as-obtained hollow MONPs has been demonstrated in the loading and pH-responsive release of thiamethoxam (THI). The resultant THI-loaded MONPs possessed long-term storage stability at a low temperature and showed release behaviors in response to a basic environment. Benefiting from the shielding property of MONPs, THI-loaded MONPs manifested superior stability against the photolysis as compared to that of the THI technical. This work provides a new consideration for promoting the advancement of nanotechnology in agricultural fields.

Abstract
Solution self-assembly of amphiphilic block copolymers (BCs) is typically performed by a solvent-to-water exchange. However, BC assemblies are often trapped in metastable states depending on the mixing conditions such as the magnitude and rate of water addition. BC self-assembly can be performed under near thermodynamic control by dialysis, which accounts for a slow and gradual water addition. In this Letter we report the use of a specifically designed dialysis cell to continuously monitor by dynamic light scattering and small-angle neutron scattering the morphological changes of PDMS-b-PEG BCs self-assemblies during THF-to-water exchange. The complete phase diagrams of near-equilibrium structures can then be established. Spherical micelles first form before evolving to rod-like micelles and vesicles, decreasing the total developed interfacial area of self-assembled structures in response to increasing interfacial energy as the water content increases. The dialysis kinetics can be tailored to the time scale of BC self-assembly by modifying the membrane pore size, which is of interest to study the interplay between thermodynamics and kinetics in self-assembly pathways.

Abstract
It is highly desirable to develop smart and green pesticide nanoformulations for improving pesticide targeting and reducing their inherent toxicity. Herein, we demonstrate a continuous nanoprecipitation method to construct a novel type of enzyme-responsive fluorescent nanopesticides (denoted as ABM@BSA-FITC/GA NPs) based on abamectin, fluorescein isothiocyanate isomer (FITC)-modified protein, and food-grade gum arabic. The as-prepared ABM@BSA-FITC/GA NPs exhibit good water dispersibility, excellent storage stability, and enhanced wettability compared to commercial formulations. The controlled release of pesticides can be achieved through protein degradation caused by trypsin. Most importantly, the deposition, distribution, and transport of the ABM@BSA-FITC/GA NPs are precisely tracked on target plants (cabbage and cucumber) by fluorescence. Furthermore, the ABM@BSA-FITC/GA NPs show the high control efficacy against Plutella xylostella L., which is comparable with commercial emulsifiable concentrate formulation. In consideration of its eco-friendly composition and absence of organic solvent, this pesticide nanoformulation has promising potential in sustainable plant protection.

Abstract
Green delivery carriers of nanopesticides, like sophorolipid biosurfactants, are of great significance to reduce environmental pollution and promote sustainable agricultural development. However, the molecular diversity of an unisolated sophorolipid mixture with almost unpredictable self-assembly properties has limited the in-depth study of its structure-activity relationship and hindered the development of green pesticide delivery systems. In this work, the acidic and lactonic sophorolipids were successfully separated from the sophorolipid mixture through silica gel column chromatography. A series of cost-effective green nanopesticides loaded with lambda-cyhalothrin (LC) were rapidly fabricated based on a combination of the acidic and lactonic sophorolipids as surfactants by flash nanoprecipitation. The effects of the acidic-to-lactonic ratio on particle size, drug loading capacity, and biological activity against Hyphantria cunea of LC-loaded nanoparticles were systematically investigated. The resultant nanopesticides exhibited a better insecticidal efficacy than a commercial emulsifiable concentrate formulation. This work opens up a novel strategy to construct scalable, cost-effective, and environmentally friendly nanopesticide systems.
