Abstract
Nanosized biomimetics prepared by the strategy of molecular imprinting, that is, the stamping of recognition sites by means of a template-assisted synthesis, are demonstrating potential as plastic antibodies in medicine, proving effective for cell imaging and targeted therapies. Most molecularly imprinted nanoparticles (MIP-NPs) are currently made of soft matter, such as polyacrylamide and derivatives. Yet, MIP-NPs biocompatibility is crucial for their effective translation into clinical uses. Here, we propose the original idea to synthesize fully biocompatible molecularly imprinted nanoparticles starting from the natural polymer silk fibroin (MIP SF-NPs), which is nontoxic and highly biocompatible. The conditions to produce MIP SF-NPs of different sizes (dmean ∼ 50 nm; dmean ∼ 100 nm) were set using the response surface method. The stamping of a single, high affinity (KD = 57 × 10-9 M), and selective recognition site per silk fibroin nanoparticle was demonstrated, together with the confirmation of nontoxicity. Additionally, MIP SF-NPs were used to decorate silk microfibers and silk nanofibers, providing a general means to add entailed biofunctionalities to materials.

Abstract
Molecular imprinting is an approach of generating imprinting cavities in polymer structures that are compatible with the target molecules. The cavities have memory for shape and chemical recognition, similar to the recognition mechanism of antigen-antibody in organisms. Their structures are also called biomimetic receptors or synthetic receptors. Owing to the excellent selectivity and unique structural predictability of molecularly imprinted materials (MIMs), practical MIMs have become a rapidly evolving research area providing key factors for understanding separation, recognition, and regenerative properties toward biological small molecules to biomacromolecules, even cell and microorganism. In this review, the characteristics, morphologies, and applicability of currently popular carrier materials for molecular imprinting, especially the fundamental role of hydrogels, porous materials, hierarchical nanoparticles, and 2D materials in the separation and recognition of biological templates are discussed. Moreover, through a series of case studies, emphasis is given on introducing imprinting strategies for biological templates with different molecular scales. In particular, the differences and connections between small molecular imprinting (bulk imprinting, "dummy" template imprinting, etc.), large molecular imprinting (surface imprinting, interfacial imprinting, etc.), and cell imprinting strategies are demonstrated in detail. Finally, future research directions are provided.

Abstract
A versatile strategy, based on the use of an amphiphilic copolymer as a macromonomer, was developed for the preparation of a fully synthetic MIP (molecularly imprinted polymer) sensor for protein recognition. A UV-crosslinkable copolymer poly(DMA-co-HEA-co-St) (UPDHS) was designed and synthesized to assemble with the template protein in aqueous solution, resulting in the fabrication of protein imprinted polymeric nanoparticles. Linear macromolecular chains were used to protect the structural integrity of the protein, through which a 3D structure was formed around the protein molecule to generate recognition cavities. Then the nanoparticles were immobilized on the cleaned surface of a transducer as an MIP sensing platform. The resultant MIP coating was then irradiated via ultraviolet light to ensure that the recognition cavities were stable after UV curing. After protein extraction, recognition cavities complementary to the protein molecule in shape, size and chemical functionality were formed in the platform, which could then selectively rebind to the template in a mixture of closely related compounds. The sensor exhibited satisfactory selectivity, a wide linear range from 10-14 to 10-9 mg mL-1, and a comparatively lower detection limit for protein detection. This strategy offers a new and straightforward method for the synthesis of receptors for label-free and cost-efficient protein recognition. This is one of the most effective and versatile strategies for the preparation of high-performance protein recognition devices based on a fully synthetic MIP.
