The antibodies themselves are obtained from large mammals and are further modified with enzymes. In this study, we developed novel recombinant immunoglobulin G (IgG)-binding luciferase-based signal amplifiers (rILSAs) by genetically fusing luciferase (Nluc) with antimouse IgG1 nanobody (MG1Nb) and antibody-binding domain (ABD), individually or together, in a mix-and-match manner. We obtained three different highly pure rILSAs in large quantities using a bacterial overexpression system and one-step purification. Mouse-specific rILSA, MG1Nb-Nluc, and rabbit-specific rILSA, Nluc-ABD, selectively bound to target-molecule-bound mouse IgG1 and rabbit IgG primary antibodies, whereas the bispecific rILSA, MG1Nb-Nluc-ABD, mutually bound to both mouse IgG1 and rabbit IgG primary antibodies. All rILSAs exhibited an outstanding signal-amplifying capability comparable to those of conventional horseradish-peroxidase-conjugated secondary antibodies, regardless of the target molecules, in various immunoassay formats, such as enzyme-linked immunosorbent assay, Western blot, and lateral flow assays. Each rILSA was selected for its own individual purpose and applied to various types of target analytes, in combination with a variety of target-specific primary antibodies, effectively minimizing the use of animals as well as reducing the costs and time associated with the production and chemical conjugation of signal-amplifying enzymes.Renewable biobased porous aerogels with excellent biodegradability have versatile applications in oil/water separation, catalysis, and tissue engineering. However, processing of the porous matrix is challenging due to the high e
