Abstract: The embodiments of the disclosure provide a method, apparatus, device and storage medium for presenting information, which relate to the technical field of computers. The method includes: obtaining object search information, in response to the object search information being object category information, determining a target object category corresponding to the object search information, and presenting object information of a plurality of target objects corresponding to the target object category in a search result presentation page; where all the plurality of target objects are different, and object information of a target object includes object attribute information and image resource information of the target object. By employing the above technical solution, when the user is searching the object category, object information of a plurality of target objects different from each other corresponding to the target object category is presented in the search result page.

Abstract: Some embodiments of the disclosure provide a method for detecting an anti-chimeric antigen receptor (CAR) antibody against humanized CAR T cells. In some examples, the method include following steps. S1. Transfecting a humanized CAR into Chinese hamster ovary (CHO) cells into using lentivirus to generate CHO cells expressing CAR as target cells. S2. Collecting samples to be tested. S3. Preparing different concentrations of standards using human proteins corresponding to a target of the CAR and establishing a standard curve. S4. Incubating the target cells with the different concentrations of standards and the samples to be tested, and capturing the anti-CAR antibody. S5. Incubating a phycoerythrin (PE)-conjugated anti-human IgG Fc antibody with CHO cells for labeling. S6. Calculating the anti-CAR antibody by detecting average fluorescence intensities of the standards, blank control, and the samples to be tested using flow cytometry.

Abstract: The present disclosure belongs to the field of single-atom catalytic degradation of refractory organic pollutants, and provides a single-atom catalyst for activation of persulfate to generate pure singlet oxygen (1O2) as well as a preparation method and an application thereof. The single-atom catalyst of the present disclosure includes supports and single iron atoms loaded on the support; the supports are graphitic carbon nitride nanosheets; the single iron atoms are bound to the supports in the form of a Fe—N4 coordination structure. The present disclosure employs graphitic carbon nitride nanosheets as the supports, so that the single iron atoms have a uniform surrounding environment and the persulfate is only converted into 1O2 when being activated; 1O2 has good selectivity and anti-interference ability, so the single-atom catalyst provided in the present disclosure may have excellent selectivity and anti-interference performance in the degradation of organic pollutants.
