Abstract
Nanoparticles have been widely used in important biomedical applications such as imaging, drug delivery, and disease therapy, in which targeting toward specific proteins is often essential. However, current targeting strategies mainly rely on surface modification with bioligands, which not only often fail to provide desired properties but also remain challenging. Here an unprecedented approach is reported, called reverse microemulsion-confined epitope-oriented surface imprinting and cladding (ROSIC), for facile, versatile, and controllable engineering coreless and core/shell nanoparticles with tunable monodispersed size as well as specific targeting capability toward proteins and peptides. Via engineering coreless imprinted and cladded silica nanoparticles, the effectiveness and superiority over conventional imprinting of the proposed approach are first verified. The prepared nanoparticles exhibit both high specificity and high affinity. Using quantum dots, superparamagnetic nanoparticles, silver nanoparticles, and upconverting nanoparticles as a representative set of core substrates, a variety of imprinted and cladded single-core/shell nanoparticles are then successfully prepared. Finally, using imprinted and cladded fluorescent nanoparticles as probes, in vitro targeted imaging of triple-negative breast cancer (TNBC) cells and in vivo targeted imaging of TNBC-bearing mice are achieved. This approach opens a new avenue to engineering of nanoparticles for targeting specific proteins, holding great prospects in biomedical applications.

Abstract
Myoglobin (Mb) is an ideal biochemical marker for the diagnosis of certain diseases caused by damage to heart muscle or skeletal muscle. Nevertheless, serum myoglobin levels are usually very low while the interference components in real sample are extremely abundent. Hence, it is of great clinical significance to establish an effective method for Mb targeting. To obtain desired selectivity, targeting biomolecules like antibody and aptamer are essential to 'the state of the art'. However, such biomolecules suffer from many disadvantages, such as hard to prepare, susceptible to protease degradation, and high cost. Thus, novel alternatives that can overcome these issues are highly desirable. Herein, we pioneered a template-anchored controllable surface imprinting strategy for selective extraction of Mb from human serum via combining with facile magnetic separation of magnetic nanoparticles (MNPs). Mb-imprinted MNPs, as antibody-biomimetic materials, were prepared using amino group-modified MNPs as substrates and water-soluble self-polymerizable dopamine as imprinting monomer. The optimized imprinting time was 70 min, giving an optimal performance with high practical imprinting efficiency (up to 41%), high imprinting factor (4.2), high binding affinity (Kd=(2.05 ± 0.09) × 10-5 M), as well as excellent recognition selectivity. Moreover, compared to bare MNPs, Mb-imprinted MNPs possessed markedly better pH tolerance. Finally, the selective extraction of Mb from human serum sample by Mb-imprinted MNPs was experimentally confirmed and the recoveries of Mb in spiked serum ranged from (91.12 ± 6.81)% to (107.99 ± 7.76)%, indicating that the Mb-imprinted MNPs could be competent for the selective analysis of Mb in real bio-samples like human serum with high precision and reliability.

Abstract
Capillary electrophoresis (CE) and magnetic beads have been widely used for the selection of aptamers owing to their efficient separation ability. However, these methods alone are associated with some apparent drawbacks. CE suffers from small injection volumes and thereby only a limited amount of aptamer can be collected at each round. While the magnetic beads approach is often associated with tedious procedure and nonspecific binding. Herein we present a hybrid approach that combines the above two classical aptamer selection methods to overcome the drawbacks associated with these methods alone. In this hybrid method, one single round selection by boronate affinity magnetic nanoparticles (BA-MNPs) was first performed and then followed by a CE selection of a few rounds. The BA-MNPs-based selection eliminated nonbinding sequences, enriching effective sequences in the nucleic acid library. While the CE selection, which was carried out in free solutions, eliminated steric hindrance effects in subsequent selection. Two typical glycoproteins, Ribonuclease B (RNase B) and alkaline phosphatase (ALP), were used as targets. This hybrid method allowed for efficient selection of glycoprotein-binding aptamers within 4 rounds (1 round of BA-MNPs-based selection and 3 rounds of CE selection) and the dissociation constants reached 10-8 M level. The hybrid selection approach exhibited several significant advantages, including speed, affinity, specificity, and avoiding negative selection. Using one of the selected ALP-binding aptamers as an affinity ligand, feasibility for real application of the selected aptamers was demonstrated through constructing an improved enzyme activity assay.

Abstract
Pressure-driven remobilization without an applied electric field is shown to be possible with capillary isoelectric focusing using packed capillaries. The capillary dimensions are 100 μm i.d. and 2 cm in length, and the packing is made of 0.9 μm nonporous silica particles that are chemically modified with a brush layer of polyacrylamide. Both reversible and irreversible adsorption are shown to be negligible. The packed capillaries eliminate the problem of unwanted hydrodynamic flow between reservoirs. Three proteins are focused: trypsin inhibitor, carbonic anhydrase II, and myoglobin. The time required for focusing in the packed capillaries is increased by only a factor of 2 compared to the open capillary, giving complete focusing in less than 15 min at 200 V/cm. The packed capillaries allow the use of higher electric fields, with resolution continually increasing up to at least 1500 V/cm. The packing obstructs diffusional broadening after the field is turned off: for trypsin inhibitor, D = 6.1(±0.3) × 10(-8) cm(2)/s for the packed capillary vs D = 28.8(±0.3) × 10(-8) cm(2)/s for the open capillary. The broadening contributed by the packing during remobilization is from eddy diffusion, and it is described by its plate height, H, which is the variance per unit length: H = σ(2)/L = 0.64 μm. This limits the resolution to 0.1 pH units for the 2 cm capillary having a pH range of 3-10, giving a theoretical peak capacity of 47.
