Electrochemical Detection of Dopamine Release from Living Neurons Using Graphene Oxide-Incorporated Polypyrrole/Gold Nanocluster Hybrid Nanopattern Arrays.

Stem-cell-based therapeutics have shown immense potential in treating various diseases that are currently incurable. In particular, partial recovery of Parkinson's disease, which occurs due to massive loss or abnormal functionality of dopaminergic (DAnergic) neurons, through the engraftment of stem-cell-derived neurons ex vivo is reported. However, precise assessment of the functionality and maturity of DAnergic neurons is still challenging for their enhanced clinical efficacy.

Lateral interactions between CD276 and CD147 are essential for stemness in breast cancer: a novel insight from proximal proteome analysis.

Oncogenic cell-surface membrane proteins contribute to the phenotypic and functional characteristics of cancer stem cells (CSCs). We employed a proximity-labeling proteomic approach to quantitatively analyze the cell-surface membrane proteins in close proximity to CD147 in CSCs. Furthermore, we compared CSCs to non-CSCs to identify CSC-specific cell-surface membrane proteins that are closely interact with CD147 and revealed that lateral interaction between CD147 and CD276 concealed within the lipid raft microdomain in CSCs, confers resistance to docetaxel, a commonly used chemotherapy agent for various cancer types, including metastatic breast cancer.

Multivalent Maxibody with a Broad Spectrum of Strain Specificity and Sensitivity for Gonorrhea Diagnosis.

Gonorrhea is one of the most common, but still hidden and insidious, sexually transmitted diseases caused by (). However, the diagnosis and treatment of gonorrhea are hampered by antigenic variability among , the lack of acquired immunity, and antimicrobial resistance. Further, strains resistant to cephalosporins, including ceftriaxone, the last line of defense, represent a growing threat, which prompted us to develop -specific diagnostic antibodies with broad-spectrum binding to strains to generate gonorrhea-detecting reagents.

Rapid Evaluation of Antibody Fragment Endocytosis for Antibody Fragment-Drug Conjugates.

Antibody-drug conjugates (ADCs) have emerged as the most promising strategy in targeted cancer treatment. Recent strategies for the optimization ADCs include the development of antibody fragment-drug conjugates (FDCs). The critical factor in the successful development of ADCs and FDCs is the identification of tumor antigen-specific and internalizing antibodies (Abs).

Fabrication of poly-silicon nano-wire transistors on plastic substrates.

We report the fabrication and characterization of poly-Si nanowire transistors on flexible substrates. The nanowire transistors are fabricated on a SiO2/Si substrate using conventional CMOS processes, and then they are transferred onto polyimide substrates. The transfer process is performed by spin-coating of polyimide, curing (annealing) of the polyimide layer, and removal of the SiO2 sacrificial layer.
