The present invention relates to a reference current circuit. The reference circuit comprises a low-level current bias circuit, a voltage proportional-to-absolute temperature generator for creating a proportional-to-absolute temperature voltage (VPTAT), and a MOSFET-based constant-IC regulator circuit. The MOSFET-based constant-IC regulator circuit includes a constant-IC input and constant-IC output. The constant-IC input is electrically connected with the VPTAT generator such that the voltage proportional-to-absolute temperature is the input into the constant-IC regulator circuit. Thus the constant-IC output maintains the constant-IC ratio across any temperature range.

A composition used to develop a reagent for investigating Ubl-modifications in cellular functions and in the treatment of cancer is provided. The composition comprises gold nanoparticle (AuNP)-ligand conjugates that include at least two components: gold nanoparticles (AuNPs) and modified ubiquitin- or ubiquitin-like interacting motif (UIM or ULIM) mimetics. In one embodiment, the modified ULM mimetic is a modified SUMO interaction motif (SIM) mimetic. According to the embodiments described herein, the compound inhibits ubiquitin- or ubiquitin-like protein (Ubl)-mediated protein-protein interactions and sensitizes cells to ionizing radiation. The modified UIM and ULIM mimetics may be conjugated to the AuNP such that each AuNP is conjugated to a plurality of modified UIM or ULIM mimetics. The modified ULIM mimetics may be conjugated to the AuNP via a thiol group.
