selective tyrosine functionalization strategy through SuFEx (sulfur fluoride exchange) chemistry is presented. In this approach, free tyrosine (Tyr) reacts selectively with aryl fluorosulfate in the presence of various nucleophilic amino acid residues in bio‐tolerable conditions. Chemoselectivity of this unique SuFEx reaction was confirmed in amino acid, peptide, and protein conjugations. The functions

Advancements in solid tumor (e.g., renal cell carcinoma) treatments and imaging are described. The advancements are based on nanoformulations that: (i) overcome deliverability issues associated with anti-cancer compounds; (ii) have increased targeted delivery to tumors, and hypoxic cores of tumors due to the presence of targeting ligands; (iii) have increased delivery to the hypoxic cores of tumors due to engineered shapes; (iv) provide synergistic treatment combinations; and/or (v) overcome cancer cell resistance to therapeutic treatments.

multigram-scale synthesis, characterization and application of a rhodamine B-based fluorophore (ROSA) suitable for fluorescent studies in biological applications. This fluorophore is devoid of rhodamine spirolactone formation and furthermore characterized by a high molar extinction coefficient (ϵ=87250 ± 1630 M-1cm-1) and quantum yield (φ) of 0.589 ± 0.070 in water. Reported here is also the application of ROSA
