Abstract: The present invention relates generally to nucleic acid molecules in respect of which changes to DNA methylation levels are indicative of the onset or predisposition to the onset of a neoplasm. More particularly, the present invention is directed to nucleic acid molecules in respect of which changes to DNA methylation levels are indicative of the onset and/or progression of a large intestine neoplasm, such as an adenoma or adenocarcinoma. The DNA methylation status of the present invention is useful in a range of applications including, but not limited to, those relating to the diagnosis and/or monitoring of colorectal neoplasms, such as colorectal adenocarcinomas. Accordingly, in a related aspect the present invention is directed to a method of screening for the onset, predisposition to the onset and/or progression of a neoplasm by screening for modulation in DNA methylation of one or more nucleic acid molecules.

Abstract: A universal chirality sensor based on immuno-recognition-driven nanoparticle assembly has been fabricated. The design of smart 10 nm AuNP-antigen and 20 nmAuNP-antibody described for the detection of aflatoxin B1. 10 nm AuNP-antigen and 20 nmAuNP-antibody assemble to symmetric plasmonic nanoparticle dimers, which induced CD signal. The addition of aflatoxin B1 to the chirality sensor resulted in transverse CD signal compared to a blank control as shown by CD measurements. This process also allowed the rapid and facile determination of concentrations of aflatoxin B1 in drinking water (tap water). Good linearity for all calibration curves was obtained, and the limit of detection (LOD) for aflatoxin B1 was 0.02 ng/mL in tap water.

Abstract: Sample preparation can be a tedious and time consuming task. For example, MALDI imaging of tissue samples can require the tedious process of hand or robotically spotting solutions containing chemical species referred to as “matrix” onto a tissue sample prior its mass spectral analysis. Provided is a process for preparing a sample comprising immersing a solid support that has a surface comprising a first part that is more hydrophilic than a second part into a target compound solution, wherein the target compound is deposited primarily onto the more hydrophilic part; and/or applying and evaporating the target compound solution onto the substrate to produce the pre-coated substrate. A tissue or other sample may then be placed on the substrate for analysis.
