Abstract
To control pandemics, a universal adjuvant platform that can deliver antigens and stimulate the immune system that rapidly elicits humoral and cellular immune responses is needed, especially one that can stimulate the body's immune system to produce protective immunological memory. However, the design, composition, and mechanism of adjuvants have presented considerable challenges. The types of adjuvants currently approved in clinics are rare and are far from meeting the requirements of vaccine development. In this study, we prepared a yeast-derived manganese and zinc metal-organic framework (MOF) composite particle adjuvant by self-assembling Mn-MOF-74 and ZIF-8 on the surface of yeast and named it yeast@Mn-MOF-74@ZIF-8 (yMZ). yMZ was able to promote the maturation and activation of dendritic cells (DCs), enhance the uptake and presentation of antigens by DCs, increase the production of adaptive immune cells with memory, enhance humoral and cellular immune responses, and promote the activation of the germinal center. Additionally, yMZ allowed for effective control of antigen release and exhibited good biosafety in vivo. In this study, yMZ showed good adjuvant effects on subunits and inactivated vaccines, indicating that it is a next-generation adjuvant candidate with potential application prospects.

A zeolitic imidazolate framework-90 enhanced ultrasensitive ATP sensing platform with HCR and CRISPR-Cas12a dual signal amplification for live bacteria detection. JOURNAL OF HAZARDOUS MATERIALS 2025; 494:138612. [PMID: 40378737 DOI: 10.1016/j.jhazmat.2025.138612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2025] [Revised: 04/20/2025] [Accepted: 05/12/2025] [Indexed: 05/19/2025]
Abstract
Bacteria are prevalent environmental pollutants. Live bacteria can proliferate and spread under appropriate conditions, presenting higher risks compared to non-viable counterparts. However, detecting live bacteria remains a challenge. Adenosine triphosphate (ATP), an energy currency in organisms, offers a reliable biomarker for the live bacteria sensing. Herein, we developed a zeolitic imidazolate framework-90 (ZIF-90) enhanced ATP sensing platform to detect live bacteria. The nanosystem which based on ZIF-90, encapsulating the DNA decorated magnetic beads (MB@S1) through self-assembly. When the S. aureus aptamers on ZIF-90 bonded to bacteria, the skeleton structure of ZIF-90 was disrupted by ATP leakage from live bacteria, leading to the release of MB@S1. Then, the MB@S1 initiated the hybridization chain reaction (HCR) and they were transduced by CRISPR-Cas12a to amplify the signal twice. The proposed ZIF-90 blocking sensing strategy (ZIF-90 strategy) exhibited remarkable sensitivity with the limit of detection (LOD) down to 0.223 pM for ATP detection, about 500 folds lower than the traditional ATP aptamer blocking sensing strategy (aptamer strategy). Furthermore, we used a smartphone for on-site analysis, realizing the quantification of live S. aureus with the LOD of 2.0 CFU/mL. Therefore, the approach possessed great application potential for public health, environment monitoring, bioanalysis and food safety.

Ultrarobust stable ABTS radical cation prepared using Spore@Cu-TMA biocomposites for antioxidant capacity assay. Talanta 2024; 276:126282. [PMID: 38788382 DOI: 10.1016/j.talanta.2024.126282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/26/2024] [Accepted: 05/17/2024] [Indexed: 05/26/2024]
Abstract
Herein, spore@Cu-trimesic acid (TMA) biocomposites were prepared by self-assembling Cu-based metal-organic framework on the surface of Bacillus velezensis spores. The laccase-like activity of spore@Cu-TMA biocomposites was enhanced by 14.9 times compared with that of pure spores due to the reaction of Cu2+ ions with laccase on the spore surface and the microporous structure of Cu-TMA shell promoting material transport and increasing substrate accessibility. Spore@Cu-TMA rapidly oxidized and transformed 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) into ABTS●+ without using H2O2. Under optimum conditions, the ABTS●+ could be stored for 21 days at 4 °C and 7 days at 37 °C without the addition of any stabilizers, allowing for the large-scale preparation and long-term storage of ABTS●+. The ultrarobust stable ABTS●+ obtained with the use of Cu-TMA could effectively reduce the "back reaction" by preventing the leaching of the metabolites released by the spores. On the basis of these findings, a rapid, low-cost, and eco-friendly colorimetric platform was successfully developed for the detection of antioxidant capacity. Determination of antioxidant capacity for several antioxidants such as caffeic acid, glutathione, and Trolox revealed their corresponding limits of detection at 4.83, 8.89, and 7.39 nM, respectively, with linear ranges of 0.01-130, 0.01-140, and 0.01-180 μM, respectively. This study provides a facile way to prepare ultrarobust stable ABTS●+ and presents a potential application of spore@Cu-TMA biocomposites in food detection and bioanalysis.

Abstract
Amorphous metal-organic framework (aMOF)-based materials have attracted considerable attention as an emerging class of nanomaterials. Herein, novel microorganisms@aMIL-125 (Ti) composites including yeast@aMIL-125 (Ti), PCC 6803@aMIL-125 (Ti), and Escherichia coli@aMIL-125 (Ti) composites were respectively synthesized by self-assembling aMOFs on the microorganisms' surface. The functional groups on the microorganisms' surface induced structural defects and participated in the formation of aMIL-125 (Ti) composites. Finally, the application of microorganisms@aMIL-125 (Ti) composites for the removal of glyphosate from aqueous solution was selected as a model reaction to illustrate their potential for environmental protection. The present method is not only economical but also has other advantages including ease of operation, environmentally friendly assay, and high adsorption. The maximum adsorption capacity of aMIL-125 (Ti) was 1096.25 mg g-1, which was 1.74 times that of crystalline MIL-125 (Ti). Therefore, the microorganisms@aMOFs composites will have broad application prospects in energy storage, drug delivery, catalysis, adsorbing toxic substances, sensing, encapsulating and delivering enzymes, and in other fields.

Abstract
Vaccines have been one of the most powerful weapons to defend against infectious diseases for a long time now. Subunit vaccines are of increasing importance because of their safety and effectiveness. In this work, a Bacillus amyloliquefaciens spore@zeolitic imidazolate framework-8 (ZIF-8) vaccine platform is constructed. The ovalbumin (OVA) is encapsulated in the ZIF-8 shells as a model antigen to form a spore@OVA@ZIF-8 (SOZ) composite. The assembly of ZIF-8 improves the loading content of OVA on the spores and provides OVA with long-term protection. The SOZ composite enhances the immunization efficacy in multiple ways, such as facilitation of antigen uptake and lysosome escape, stimulation of dendritic cells to mature and secrete cytokines, boosting of antibody production and formation of an antigen depot. This platform shows several advantages including easy preparation, cost-effectiveness, long life, convenience of transportation and storage, and no need for the cold chain. These findings may have promising implications for the rational design of safe and effective spore-based composite vaccine platforms.
