University of Bath, UK develops graphene-based non-invasive, transdermal glucose monitoring sensor

Worldwide, the incidence of diabetes is increasing, and the monitoring of blood glucose levels in the human body has become the basic guarantee for the care of diabetic patients. At present, the main blood glucose monitoring method is realized by invasive blood collection of fingers, which will inevitably bring about certain pain and discomfort. Recently developed implantable and microneedle sensors cannot be applied to most types 2 Diabetic patients. Therefore, as of now, there is no relevant report on the needle-free method for blood glucose monitoring in diabetic patients.

Recently, Professor Adelina Ilie of the University of Bath in the United Kingdom designed and constructed a new in vivo glucose monitoring system. This non-invasive blood glucose monitoring system can be attached to the wrist and can monitor blood sugar without blood collection. The blood glucose monitoring function is realized by a series of miniature sensors built into the wrist blood glucose monitoring system, in which each sensor can absorb glucose from the vicinity of a single hair follicle under the action of a small current, store it in a micro device in the wristband, and measure it. .

According to the researchers, the most important raw material for this wrist blood glucose monitoring system is graphene, which has many characteristics such as conductivity, softness and environmental protection. This research is of great value for the development of non-invasive blood glucose monitoring for diabetic patients and the like. The study also found that the system was able to monitor blood glucose levels in the human body continuously (6 hours). The research results were published in the journal Nature Nanotechnology, the original title is Non-invasive, transdermal, path-selective and specific glucose monitoring via a graphene-based platform.

The graphene-based glucose monitoring platform has the advantages of low cost, flexibility and high throughput, and is expected to promote non-invasive monitoring of glucose concentration in the human body.

A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.


The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.


But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
